Thereby, the effect that the bowl part can be effectively dehumidified both when the humidity of the arrangement space is low and when it is high is obtained.

Hereinafter, the configuration of the present embodiment will be described in detail.
The toilet device 1 is of a tankless type that is directly connected to a water pipe, and includes a toilet body 11 that holds the bowl portion 10, a toilet seat 12, and a toilet lid 13.

  The toilet body 11 incorporates an electromagnetic valve and a trap mechanism (not shown) for controlling the discharge and supply of cleaning water, a local cleaning mechanism 14 for cleaning the toilet user's local area, and the like. The toilet body 11 is also provided with a humidity sensor 15, a lid position sensor 16, a human sensor 17, a sterilized water spray device 25, and the like. The humidity sensor 15 may be provided in any part of the toilet device 1 as long as the humidity of the arrangement space can be detected. The disinfecting water spraying device 25 has a function of generating and spraying ozone water from tap water. Such a disinfecting water spraying device is known.

  The control part 18 consists of a microcomputer board etc., and controls each part of the toilet device 1 according to a control program. The operation unit 19 is a remote control type, and is configured to communicate with the control unit 17 by wire or wirelessly.

  The bowl part 10 and the toilet body 11 are made of ceramic or resin. These may be formed integrally or may be formed as a separate body and then integrated with an adhesive or the like. The bowl part 10 is connected to a sewer pipe through a trap mechanism or the like from a drain outlet provided at the bottom part.

  Further, the bowl portion 10 has a cleaning water channel 20 formed in a groove along the upper edge thereof, that is, a rim back portion. The cleaning water channel 20 has a lateral groove shape with an open inner surface, and substantially goes around the rim back portion. A cleaning water discharge port 21 is provided at the start end of the cleaning water channel 20. When washing water is discharged from the washing water discharge port 21 based on the toilet user's washing operation, the washing water flows while being kept in the washing water channel 20 by the action of centrifugal force. Wash water overflowing downward from 20 cleans the entire bowl portion 10.

  The bowl dehumidifying device 22 has a function of supplying warm air to the bowl part 10 and a function of ventilating the bowl part 10, but the structure and configuration thereof are not particularly limited. For example, a unit for supplying warm air to the bowl unit 10 and a unit for ventilating the bowl unit 10 as the bowl dehumidifying device 22 may be provided separately. Or the bowl dehumidification apparatus 22 may be comprised as a single unit which can switch a warm air supply function and a ventilation function. In the present embodiment, such a single unit is used as the bowl dehumidifier 22.

  Specifically, the bowl dehumidifier 22 communicates a bowl vent 22a that opens to the bowl portion 10 and a housing vent 22b that opens to the outer surface of the toilet body 11 by a duct 22c, and a blower device 23 at the middle portion thereof. And a heater 24 are provided as a basic configuration.

  The bowl vent 22a is disposed on the upper edge of the rear portion of the bowl portion 10, and is provided with a louver (gull) for preventing the ingress of cleaning water or the like. The housing vent 22b is disposed at a middle position on the back surface of the toilet body 11, and is opened downward. The duct 22c is a chemically stable resin or metal cylinder, and its shape and structure are not particularly limited. The blower device 23 may be a general device using a propeller fan or the like. The heater 24 may be a general one using a heating wire or the like (sheath heater or the like).

  The bowl dehumidifying device 22 having such a configuration can supply hot air to the bowl portion 10 by operating the blower device 23 in the forward direction (intake direction) while energizing the heater 24. Further, the bowl dehumidifying device 22 can ventilate the bowl portion 10 by operating the blower device 23 in the reverse direction (exhaust direction) without energizing the heater 24. Of course, it is also possible to ventilate the bowl portion 10 by operating the blower device 23 in the forward direction.

Next, the basic operation of the bowl dehumidifier 22 will be described.
The bowl dehumidifying device 22 is basically operated after washing the bowl part or after spraying the sterilized water. In this case, it is assumed that the toilet lid 13 is closed. When the toilet lid 13 is open, the bowl portion 10 and the arrangement space are completely connected. Therefore, even if the bowl dehumidifying device 22 is operated, an effect cannot be expected.

  When the toilet lid 13 is closed, the bowl portion 10 and the arrangement space communicate with each other by a gap between the toilet lid 13 and the toilet body 11. However, since the bowl portion 10 has accumulated water, the humidity of the bowl portion 0 is basically slightly higher than the humidity of the arrangement space. Therefore, when the humidity of the arrangement space is low, the bowl dehumidifying device 22 can dehumidify by ventilating the bowl portion 10.

  On the other hand, even if the bowl part 10 is ventilated when the humidity of the arrangement space is high, it is difficult to dehumidify the bowl part 10 because the humidity of the air flowing in from the arrangement space with ventilation is high. However, at this time, if the bowl dehumidifying device 22 sucks air from the arrangement space and heats it and supplies it to the bowl part 10 as warm air, the air with reduced humidity is supplied to the bowl part 10, so that the dehumidification is good. it can.

For the above reasons, the bowl dehumidifying device 22 may determine whether to supply hot air to the bowl unit 10 or ventilate the bowl unit 10 based on the humidity of the arrangement space. Here, a constant value of 50% to 60% humidity may be adopted as a threshold value for determining the humidity level of the arrangement space.
As a specific example, the bowl dehumidifying device 22 supplies hot air to the bowl part if the humidity of the arrangement space is ≧ 55%,
If the humidity of the arrangement space is <55%, the bowl portion may be controlled to be ventilated. ... (a)

When the window of the arrangement space is opened during heavy rain, the humidity of the bowl portion 10 may be higher than the humidity of the arrangement space. If the bowl part 10 is ventilated at such time, dehumidification will not be performed satisfactorily. In order not to cause such a situation, the toilet device 1 further includes a bowl humidity sensor 26 that detects the humidity of the bowl unit 10, and the bowl dehumidifying device 22 is configured so that the humidity of the arrangement space is higher than the humidity of the bowl unit 10. Hot air may be supplied to the bowl unit 10.
That is, the bowl dehumidifier 22 considers the control (a),
If (the humidity of the arrangement space ≧ 55%) and (the humidity of the arrangement space <the humidity of the bowl portion), supply warm air to the bowl portion 10,
If (humidity of arrangement space <55%) and (humidity of arrangement space <humidity of bowl part), ventilate the bowl part 10,
If the humidity of the arrangement space is equal to or higher than the humidity of the bowl part 10, the hot air may be supplied to the bowl part. ... (b)

  4 (a) and 4 (b) summarize the controls (a) and (b) in a table.

  Next, an example of a basic operation related to dehumidification of the bowl portion 10 in the toilet device 1 will be described according to a flowchart.

  FIG. 5 is a flowchart illustrating an example of a control procedure for wastewater treatment. The operation related to dehumidification of the bowl portion 10 is included in this procedure. Here, the control unit 18 adopts (b) as an example.

Step 100 is a process in which the control unit 18 controls the electromagnetic valve, the trap mechanism, and the like to discharge the bowl unit 10 with water.
Step 101 is processing for determining whether or not the toilet lid 13 is closed based on the detection signal of the lid position sensor 16. Step 102 is a process for ending the procedure without dehumidifying the bowl portion 10 because the toilet lid 13 is open.
Step 103 is a process for determining the humidity in accordance with the control (b).
Step 104 is a process in which the bowl dehumidifying device 22 supplies hot air to the bowl unit 10 when the determination result in Step 103 is humidity of the arrangement space ≧ 55% and humidity of the arrangement space <humidity of the bowl unit 10. is there. Thus, after supplying warm air to the bowl portion 10 for a predetermined time, the procedure is terminated.
Step 105 is a process in which the bowl dehumidifying device 22 ventilates the bowl unit 10 when the determination result in step 103 is the humidity of the arrangement space <55% and the humidity of the arrangement space <the humidity of the bowl unit 10. After the bowl has been ventilated for a predetermined time, the procedure is terminated.
Step 106 is a process in which the bowl dehumidifying device 22 supplies hot air to the bowl unit 10 when the determination result in step 103 is humidity of the arrangement space ≧ humidity of the bowl unit 10. Thus, after supplying warm air to the bowl portion 10 for a predetermined time, the procedure is terminated.

  FIG. 6 is a flowchart illustrating an example of a control procedure of the disinfecting water spraying process. Again, the control unit 18 employs the control (b).

Step 200 is a process in which the control unit 18 determines whether or not the toilet lid 13 is closed based on the detection signal of the lid position sensor 16. Step 201 is processing for determining the presence or absence of a toilet user based on the detection signal of the human sensor 17.
Step 202 is a process of ending the procedure without spraying sterilized water on the bowl portion 10 when the result of the determination in Steps 200 and 201 is that the toilet lid 13 is open or there is a toilet user. .
Step 203 is a process of spraying sterilized water on the bowl portion 10 when the determination result in Steps 200 and 201 is that the toilet lid 13 is closed and there is no toilet user.
Step 204 is processing for determining the humidity according to the control (b).
Step 205 is a process in which the bowl dehumidifying device 22 supplies hot air to the bowl unit 10 when the determination result in Step 204 is humidity of the arrangement space ≧ 55% and humidity of the arrangement space <humidity of the bowl unit 10. It is. Thus, after supplying warm air to the bowl portion 10 for a predetermined time, the procedure is terminated.
Step 206 is a process in which the bowl dehumidifying device 22 ventilates the bowl unit 10 when the determination result in step 204 is the humidity of the arrangement space <55% and the humidity of the arrangement space <the humidity of the bowl unit 10. After the bowl portion 10 is ventilated for a predetermined time in this way, the procedure is terminated.
Step 207 is processing in which the bowl dehumidifying device 22 supplies hot air to the bowl unit 10 when the determination result in step 204 is humidity of the arrangement space ≧ humidity of the bowl unit 10. Thus, after supplying warm air to the bowl portion 10 for a predetermined time, the procedure is terminated.

Next, another example of the embodiment will be described.
7A and 7B are an overall perspective view and a partial cross-sectional view of a toilet device as another example of the embodiment. An ellipse O in FIG. 7A indicates the location of the cut surface in FIG. Elements common to the embodiment of this example are denoted by the same reference numerals and description thereof is omitted.

  The present embodiment is characterized in that the bowl side end of the duct 22c, that is, the bowl vent 22a, is opened in the vicinity of the cleaning water channel 20 for discharging the cleaning water from the upper edge of the bowl unit 10. That is, a plurality of bowl vents 22 a are arranged along the cleaning water channel 20, and hot air or air is jetted from the respective bowl vents 22 a toward the cleaning water channel 20. A duct 22c that connects the blower device 23 built in the toilet body 11 and the bowl vent 22a is accommodated in a cavity 27 formed adjacent to the upper edge of the bowl 10, specifically, the upper side of the washing water channel 20. Has been.

  Also in this embodiment, the basic operation of the bowl dehumidifier 22 is the same as that in the above embodiment. That is, the bowl dehumidifier 22 may be operated by the control (b) or the like. However, the bowl dehumidifier 22 is configured to suck air from the housing vent 22b and release it from the bowl vent 22a when the bowl portion 10 is ventilated. In this way, when supplying warm air to the bowl portion 10 or dehumidifying, it is possible to dry the washing water channel 20 where water droplets D or the like are likely to remain, so that the growth of various germs can be suppressed, which is hygienic. .

  The bowl vent 22 a may be opened inside the cleaning water channel 20, for example, deep inside the cleaning water discharge port 21. In such a case, there is an advantage that sewage or the like does not enter the bowl vent 22a, and that the bowl vent 22a is not visible when the toilet lid 13 and the toilet seat are raised, so that the appearance is good.
