FIG. 4 is a schematic cross-sectional view showing a state when the filter of this embodiment is being cleaned.
FIG. 5 is a schematic cross-sectional view showing a state when the local drying apparatus of the present embodiment blows warm air.
4 and 5 are schematic cross-sectional views taken along the cutting plane AA shown in FIG.

  As shown in FIGS. 4 and 5, a suction port 105 through which air in the bowl 801 is sucked into the deodorizing device 110 is provided on the bottom surface of the casing 100. The filter 115 of the deodorizing device 110 is installed at the suction port 105. However, the installation position of the filter 115 is not limited to this, and may be on the downstream side of the suction port 105, that is, on the suction fan 113 side of the suction port 105.

  In addition, as shown in FIG. 5, a hot air outlet 103 through which air sent from the blower fan 131 of the local drying device 130 is jetted into the bowl 801 is provided on the front surface of the casing 100. A damper 140 that can close the hot air outlet 103 is provided at the hot air outlet 103. The damper 140 is pivotally supported by the casing 100 on a shaft 141 and can be rotated around the shaft 141 by a driving force transmitted from an opening / closing drive unit having a motor 143 (see FIG. 3), for example. Therefore, the damper 140 can open and close the hot air outlet 103 by rotating about the shaft 141. At this time, the control unit 180 can control the operation of the motor 143.

  Above the suction port 105, in other words, behind the hot air outlet 103, a space 101 is provided that allows the suction port 105 and the hot air outlet 103 to communicate with each other. And the water distribution pipe 121 is installed so that this space 101 may be faced.

  Here, the filter 115 can suppress the dust derived from toilet paper or clothing from being sucked into the suction fan 113, but if the dust adheres to and accumulates on the filter 115, the filter 115 is clogged. There is a fear. Further, when small water splashed on the surface of the bowl 801 or sealed water in the bowl 801 splashed by a user's stool adheres to the filter 115, dust easily adheres to the filter 115 and accumulates. Clogging is likely to occur. If the filter 115 is clogged, the suction fan 113 of the deodorizing device 110 may not be able to suck the air in the bowl 801, or it may be difficult to suck the air. If it does so, there exists a possibility that the deodorizing performance of the deodorizing apparatus 110 may fall.

  On the other hand, in the toilet apparatus according to the present embodiment, the water distribution pipe 121 is provided so as to face the space 101. And the water supply part 120 can inject the water led by the water distribution pipe 121 toward the filter 115, as represented to FIG. Therefore, the dust that adheres to and accumulates on the filter 115 is caused to flow down into the bowl 801 by the water sprayed from the water supply unit 120. As a result, the filter 115 is washed with water jetted from the water supply unit 120. According to this, it is possible to solve the problem that the deodorizing performance of the deodorizing device 110 is deteriorated due to dust adhering to and accumulating on the filter 115, and the deodorizing performance can be maintained for a long period of time.

  In the present specification, “water” includes not only cold water but also heated hot water. And when using the hot water heated as the water sprayed by the water supply part 120, the detergency at the time of washing | cleaning the filter 115 can be improved. Thereby, the cleaning time of the filter 115 can be shortened, and the cleaning operation of the filter 115 by the water supply unit 120 can be performed efficiently.

  Here, when the water supply unit 120 injects water toward the space 101 and the filter 115 in a state where the damper 140 is opened, the water may be scattered into the bowl 801 through the hot air outlet 103. In addition, when the user is seated on the toilet seat 200 and the filter 115 is washed with the damper 140 opened, the water sprayed from the water supply unit 120 or the water splashed by the filter 115 is heated. There is a risk of splashing toward the user through the wind outlet 103.

  On the other hand, in the toilet apparatus of the present embodiment, as shown in FIG. 4, when the water supply unit 120 injects water toward the filter 115, the control unit 180 controls the operation of the motor 143. Therefore, the damper 140 is closed, that is, the damper 140 is kept closed. Therefore, the water sprayed from the water supply unit 120 and the water splashed by the filter 115 are suppressed from being scattered into the bowl 801 through the hot air outlet 103. According to this, the problem which arises by injecting water to the filter 115 can be solved, and the filter 115 can be automatically cleaned.

  However, if the filter 115 of the deodorizing apparatus 110 is left as it is after being washed with water, water such as moisture or moisture (hereinafter simply referred to as “water”) may remain on the filter 115. When the control unit 180 drives the suction fan 113 in a state where water remains in the filter 115, the water remaining in the filter 115 may be sucked into the suction fan 113. If it does so, the circuit board, lead wire, etc. which were provided in the suction fan 113 may corrode and the suction fan 113 may not operate.

  On the other hand, in the toilet apparatus according to the present embodiment, the control unit 180 sprays water from the water supply unit 120 to wash the filter 115 or after washing with water, and then the blower fan 131 of the local drying device 130. Drive. Then, the air sent from the blower fan 131 is blown to the filter 115 through the hot air duct 133 as indicated by the arrow shown in FIG. At this time, the control unit 180 more preferably closes the damper 140 by controlling the operation of the motor 143. According to this, the air sent from the blower fan 131 is suppressed from being blown into the bowl 801 through the hot air outlet 103 and is blown to the filter 115 more efficiently. The means for closing the damper 140 is not limited to the control unit 180 controlling the operation of the motor 143, but a damper opening suppression mechanism (not shown) having a stopper or the like that prevents the damper 140 from opening. It may be. Or you may drive the ventilation fan 131 so that it may become a wind pressure of the grade which the damper 140 does not open.

  In this way, the control unit 180 can dry the filter 115 by driving the blower fan 131 and can remove water adhering to the filter 115. According to this, the problem caused by jetting water to the filter 115 can be solved, and the suction fan 113 of the deodorizing device 110 does not suck water after the filter 115 of the deodorizing device 110 is automatically cleaned. Can do. Further, since the filter 115 can be washed with water without removing it from the casing 100, the maintenance of the filter 115 can be simplified.

  Furthermore, since the air sent from the blower fan 131 is more efficiently blown to the filter 115 in a state where the damper 140 is closed, the water attached to the filter 115 can be removed more efficiently. According to this, energy loss can be suppressed and the suction fan 113 of the deodorizing device 110 can be prevented from sucking water after the automatic cleaning of the filter 115 of the deodorizing device 110.

  Here, when driving the blower fan 131 in order to remove the water adhering to the filter 115, the controller 180 may or may not operate the heater 135. That is, when removing water adhering to the filter 115, the local drying device 130 may blow “hot air” onto the filter 115 or “cold air” onto the filter 115.

  When the local drying device 130 blows “cold air” onto the filter 115, it is not necessary to operate the heater 135, so that energy saving can be achieved and water attached to the filter 115 can be removed.

  On the other hand, when the local drying device 130 blows “warm air” on the filter 115, the water adhering to the filter 115 can be removed in a shorter time. Therefore, the water adhering to the filter 115 can be removed more efficiently. According to this, energy loss can be suppressed and the suction fan 113 of the deodorizing device 110 can be prevented from sucking water after the automatic cleaning of the filter 115 of the deodorizing device 110.

  In addition, the control unit 180 of the present embodiment prohibits the operation of the suction fan 113 of the deodorizing device 110 and drives the odor in the bowl 801 when the blower fan 131 is driven to remove water adhering to the filter 115. The operation of sucking can be prohibited. Here, when the control unit 180 drives the suction fan 113 of the deodorizing device 110 while removing the water adhering to the filter 115, at least a part of the air sent from the blower fan 131 to the filter 115 is obtained. It is sucked into the suction fan 113. Therefore, the efficiency of removing water adhering to the filter 115 may be reduced. In addition, when the control unit 180 drives the suction fan 113 of the deodorizing apparatus 110 even though the water adhering to the filter 115 is removed, the water may be sucked into the suction fan 113.

  On the other hand, the control unit 180 of the present embodiment can prohibit the operation of the suction fan 113 of the deodorizing device 110 when the blower fan 131 is driven to remove the water adhering to the filter 115. Such a problem can be solved. That is, since the control unit 180 can prohibit the operation of the suction fan 113 of the deodorizing device 110, at least a part of the air sent from the blower fan 131 to the filter 115 is not sucked into the suction fan 113. Thereby, it can suppress that the efficiency which removes the water adhering to the filter 115 falls, and the water can be removed more efficiently. Moreover, although the water adhering to the filter 115 is removed, the water can be prevented from being sucked into the suction fan 113.

  4 and 5, the case where the moisture removing device is the local drying device 130 has been described as an example, but the moisture removing device is not limited to this. The moisture removing apparatus of this embodiment may be a heater (heating unit) 165 provided in the vicinity of the filter 115 as shown in FIGS. The control unit 180 can inject water from the water supply unit 120 to clean the filter 115 and then start the operation of the heating unit 165 to heat the filter 115 to which water has adhered.

  Thereby, the water adhering to the filter 115 can be removed in a shorter time. Therefore, the water adhering to the filter 115 can be removed more efficiently. According to this, energy loss can be suppressed and the suction fan 113 of the deodorizing device 110 can be prevented from sucking water after the automatic cleaning of the filter 115 of the deodorizing device 110.

When the seating sensor 191 makes a non-detection of the user seated on the toilet seat 200 when the user finishes the toilet and leaves the toilet seat 200, the control unit 180 sets the electromagnetic valve 125 and the three-way valve 128 to “ ON "(timing t1).

  Here, in the specification of the present application, that the control unit 180 sets the electromagnetic valve 125 to “ON” means that the control unit 180 controls the operation of the electromagnetic valve 125 and opens the electromagnetic valve 125. Further, in the present specification, when the control unit 180 sets the three-way valve 128 to “ON”, the control unit 180 controls the operation of the three-way valve 128 and supplies water supplied from the heat exchange unit 126 to the water distribution pipe 121. It shall mean guiding.

  Subsequently, when the control unit 180 sets the electromagnetic valve 125 and the three-way valve 128 to “ON” and the filter 115 is washed with water jetted from the water supply unit 120, a predetermined time elapses. The electromagnetic valve 125 and the three-way valve 128 are set to “OFF” (timing t2).

  Here, in the specification of the present application, that the control unit 180 sets the electromagnetic valve 125 to “OFF” means that the control unit 180 controls the operation of the electromagnetic valve 125 and closes the electromagnetic valve 125. In the present specification, the control unit 180 sets the three-way valve 128 to “OFF”. The control unit 180 controls the operation of the three-way valve 128, and the water supplied from the heat exchange unit 126 is supplied to the water distribution pipe 121. It shall mean not to be guided.

  Subsequently, the control unit 180 sets the electromagnetic valve 125 and the three-way valve 128 to “OFF”, and then drives the blower fan 131 of the local drying device 130 for a predetermined time (timing t3 to t4). In this series of steps, after the user leaves the toilet seat 200, the control unit 180 prohibits the operation of the suction fan 113 of the deodorizing apparatus 110 and prevents the suction fan 113 from being driven. . Thus, the control unit 180 can dry the filter 115 by driving the blower fan 131, and can remove water adhering to the filter 115. According to this, the problem caused by jetting water to the filter 115 can be solved, and the suction fan 113 of the deodorizing device 110 does not suck water after the filter 115 of the deodorizing device 110 is automatically cleaned. Can do.

  At this time, the control unit 180 controls the operation of the motor 143 to set the damper 140 to “OFF”, that is, the damper 140 is closed and not opened. As a result, as described above with reference to FIGS. 4 and 5, the air sent from the blower fan 131 is suppressed from being blown into the bowl 801 through the hot air outlet 103, and more efficiently blown onto the filter 115. It is done.

  In addition, when the blower fan 131 is driven (timing t3 to t4), the control unit 180 sets the heater 135 to “OFF”, that is, does not operate the heater 135. Therefore, “cold air” is blown to the filter 115. Thereby, as described above with reference to FIGS. 4 and 5, energy saving can be achieved and water attached to the filter 115 can be removed.

  Further, since the control unit 180 automatically cleans the filter 115 of the deodorizing apparatus 110 after the user leaves the toilet seat 200, that is, immediately after the dust adheres to the filter 115, before the dust accumulates on the filter 115. Dust can be removed. Therefore, clogging of the filter 115 can be more efficiently suppressed.

  In this specific example, when the user leaves the toilet seat 200, the control unit 180 has been described as an example in which the electromagnetic valve 125 and the three-way valve 128 are set to “ON”. The timing (t1) for setting the solenoid valve 125 and the three-way valve 128 to “ON” is not limited to this. For example, the control unit 180 may set the electromagnetic valve 125 and the three-way valve 128 to “ON” after the user leaves the toilet seat 200 and the control unit 180 causes “auto power deodorization” to be executed.

  Here, in the present specification, “auto power deodorization” means that the control unit 180 increases the output of the suction fan 113 after the user leaves the toilet seat 200, thereby increasing the amount of air sucked. , And more powerful deodorizing function. Then, after the control unit 180 executes “auto power deodorization”, the electromagnetic valve 125 and the three-way valve 128 are set to “ON”, whereby the air sent from the blower fan 131 to the filter 115 is sucked into the suction fan 113. Will not be sucked into. According to this, the water adhering to the filter 115 can be more efficiently removed, and the odor in the bowl 801 can be deodorized more quickly.

  Alternatively, when a “filter cleaning button” (not shown) provided on the casing 100 or a remote controller (not shown) is operated, the control unit 180 may set the electromagnetic valve 125 and the three-way valve 128 to “ON”. According to this, the user can automatically clean the filter 115 at a timing according to preference.

  Alternatively, after a human body detection sensor (not shown) that detects a user in front of the toilet seat 200, an entrance detection sensor (not shown) that detects a user entering the toilet room, or the like does not detect the human body, the controller 180 The electromagnetic valve 125 and the three-way valve 128 may be set to “ON”. According to this, it is possible to prevent the filter 115 from being washed when the user is seated again after leaving the toilet seat 200. That is, the control unit 180 can perform the cleaning of the filter 115 when the user is not seated on the toilet seat 200.

  Alternatively, the control unit 180 may set the electromagnetic valve 125 and the three-way valve 128 to “ON” when the time appropriately set by the timer comes. More specifically, for example, the control unit 180 may set the electromagnetic valve 125 and the three-way valve 128 to “ON” at a predetermined time with a frequency of about once a week. According to this, the filter 115 can be cleaned aiming at a time zone when the toilet device is not used at night or in the daytime. In addition, even when the time set by the timer is reached, when a human body detection sensor (not shown) detects that the user is in the toilet room, the control unit 180 stops detecting the human body. The electromagnetic valve 125 and the three-way valve 128 may be set to “ON”. According to these, since the filter 115 is cleaned when the user is not in the toilet room, the user feels uncomfortable or uncomfortable with the cleaning of the filter 115 and the driving of the blower fan 131. The feeling of pleasure can be further suppressed. Note that the time of the timer may be set in advance at the time of manufacture or shipment of the toilet device, or may be set according to preference by the user.

  Or the control part 180 may memorize | store the usage frequency of the toilet apparatus by a user, and may learn the time slot | zone with the low usage frequency. According to this, the control unit 180 can set the electromagnetic valve 125 and the three-way valve 128 to “ON” in a time zone where the frequency of use by the user is low. According to this, it is possible to execute the cleaning of the filter 115 aiming at a time zone in which the use frequency of the toilet device by the user is low. According to this, the same effect as in the case of the timer can be obtained.
