Description

  The present invention relates to a toilet seat device.

  For example, there is a deodorizing and sterilizing device for a flush toilet provided with an intake device and a sterilizing water supply device (for example, see Patent Document 1). In the deodorizing and sterilizing apparatus for flush toilets described in Patent Document 1, electrolytic water, that is, sterilizing water, is supplied to a moisturizing deodorizing filter and impregnated in order to remove malodorous components generated in a toilet or urinal. When the intake device is operated, odor is sucked from the toilet through the odor passage. When the odor passes through the deodorizing filter, the malodorous component is absorbed or decomposed by the impregnated electrolytic water.

  In such a deodorizing and sterilizing apparatus, a deodorizing effect can be obtained in a state where the filter is impregnated with electrolyzed water. Therefore, it is preferable that the filter is always kept in water during the deodorizing operation. On the other hand, during the deodorizing operation, since the air containing odor is applied to the filter by the intake device, the filter is gradually dried. For this reason, when the filter is in a dry state, water is supplied again to keep the filter impregnated with electrolytic water.

JP 2000-129747 A

However, if the electrolyzed water is supplied before the filter is completely dried, the filter is in a state of holding the electrolyzed water supplied immediately before, so the filter cannot hold the newly supplied electrolyzed water. Therefore, the electrolyzed water supplied to the filter may be wasted.
Thus, in the deodorizing and sterilizing apparatus, when deodorizing is being performed, it is preferable to keep the filter in a state of holding electrolyzed water. However, if electrolyzed water is supplied before the filter is dried, the electrolyzed water supplied by the filter is supplied. There is a problem that the water may be drained without being retained.

  The present invention has been made on the basis of such a problem. While deodorizing with a deodorizing filter, the deodorizing filter keeps the water retained, and the water discharged without being retained by the filter is removed. An object of the present invention is to provide a toilet seat device that can be reduced in number.

  In order to solve the above-described problem, the first aspect includes an apparatus main body, a suction unit that sucks air outside the apparatus main body, a deodorization filter through which the air sucked by the suction unit passes, A water supply unit that supplies water to the deodorization filter, a temperature detection unit that detects an environmental temperature, and a water supply unit that instructs the water supply unit to supply a predetermined amount of water to the deodorization filter. A drying time setting means for setting a drying time for drying the deodorizing filter to which the water of the supply water amount is supplied based on detection of the temperature detection unit, and the water of the supply water amount is set by the water supply means. After being supplied to the deodorizing filter, the deodorizing means for operating the suction unit to deodorize the air and prohibiting the supply of water by the water supplying means until the drying time has elapsed, A toilet seat apparatus, characterized in that it comprises.

According to such a configuration, the drying time setting unit sets the time until the water supplied by the water supply unit dries based on the detection of the temperature detection unit. And until this drying time passes, since execution of a water supply means is prohibited by a deodorizing means, once a water supply means is executed, the next water supply means will not be executed until the drying time passes. While the execution of the water supply unit is prohibited by the deodorizing unit, the air sucked by the suction unit passes through the deodorizing filter, so that malodorous components contained in the air outside the apparatus main body are deodorized. Moreover, the deodorizing filter gradually dries as the sucked air passes, and when the drying time elapses, the water supplied by the water supply means becomes dry. That is, in the drying time setting means, the time required for the deodorizing filter supplied with the predetermined amount of water to be dried is set as the drying time.
Therefore, the water supply means can supply water to the deodorizing filter after the drying time has elapsed and the deodorizing filter is in a dry state. As a result, more water is held in the deodorizing filter than in the case where water is supplied in a state where the deodorizing filter is not dried, and the amount of water discharged without being held in the filter can be reduced.
In addition, since water can be supplied to the deodorizing filter again after the drying time has elapsed, when deodorizing with the deodorizing filter is continued, water can be supplied again so that the deodorizing filter can maintain the state of holding the water. The odor contained in the air sucked from the section can be deodorized.

  Further, a second aspect is the first aspect, in which the drying time setting means performs the drying when the environmental temperature is higher than when the environmental temperature detected by the temperature detection unit is low. The toilet seat device is characterized in that the time is set short.

Since a predetermined amount of water is supplied from the water supply unit, the drying time required for the deodorizing filter to dry is determined by the ambient temperature of the air. That is, if the amount of water supplied is the same, the time taken for the deodorizing filter to dry is shorter when the room temperature is higher than when the environmental temperature is low.
Therefore, the drying time setting means can set the drying time according to the deodorizing filter in which the time until drying is changed according to the environmental temperature by setting the drying time shorter as the environmental temperature becomes higher.

As a result, when the environmental temperature is high, the drying time is set to be long, the water is not retained in the deodorizing filter despite the middle of the drying time, and the environmental temperature is low. It can suppress that drying time is set short and water is supplied in the state which the deodorizing filter is not drying.
Therefore, according to such a configuration, water can be supplied after the deodorizing filter is in a dry state, and water discharged without being held by the deodorizing filter can be reduced. Moreover, until the set drying time elapses, the deodorizing filter can be kept in a state of holding water.

  The third aspect includes an apparatus main body, a suction part that sucks air outside the apparatus main body, a deodorization filter through which the air sucked by the suction part passes, and water to the deodorization filter. A water supply unit to supply, a temperature detection unit for detecting an environmental temperature outside the apparatus main body, and a water supply amount setting means for setting the supply water amount to be supplied to the deodorizing filter based on the detection of the temperature detection unit And a water supply means for instructing the water supply section to supply the supply water amount to the deodorization filter, and after the water supply means supplies the water of the supply water amount to the deodorization filter, A toilet seat device comprising: a deodorizing unit that operates to deodorize the air and prohibits the supply of water by the water supply unit until a predetermined drying time elapses. .

  According to such a configuration, the water supply amount setting means sets the amount of water supplied by the water supply means based on the detection of the temperature detection unit. And since execution of a water supply means is prohibited until the drying time predetermined by the deodorizing means passes, once the water supply means is executed, the next water supply means is not executed until the drying time passes. . While the execution of the water supply unit is prohibited by the deodorizing unit, the air sucked by the suction unit passes through the deodorizing filter, so that malodorous components contained in the air outside the apparatus main body are deodorized. Moreover, the deodorizing filter gradually dries as the sucked air passes, and when the drying time elapses, the water supplied by the water supply means becomes dry. That is, in the water supply amount setting means, the amount of water in which the deodorizing filter is dried during a predetermined drying time is set as the supply water amount.

Therefore, the water supply means can supply water after the deodorizing filter is dry, and more water is supplied to the deodorizing filter than when water is supplied when the deodorizing filter is not dry. Water that is retained and discharged without being retained by the deodorizing filter can be reduced.
In addition, since water can be supplied to the deodorizing filter again after the drying time has elapsed, when deodorizing with the deodorizing filter is continued, water can be supplied again so that the deodorizing filter can maintain the state of holding the water. The odor contained in the air sucked from the section can be deodorized.

  Moreover, a 4th aspect WHEREIN: In the 3rd aspect, the said water supply amount setting means is the case where the said environmental temperature is higher compared with the case where the said environmental temperature detected by the said temperature detection part is low. The toilet seat device is characterized in that a large amount of water is set.

The amount of water evaporated from the deodorizing filter per unit time is larger when the environmental temperature is higher than when the environmental temperature of air is low. That is, for the same drying time, the amount of water evaporated from the deodorizing filter increases when the environmental temperature is higher than when the environmental temperature is low.
Therefore, the water supply amount setting means can set the supply water amount in accordance with the deodorizing filter in which the amount of water that evaporates changes in accordance with the environmental temperature by setting the supply water amount as the environmental temperature becomes higher.

Thereby, when the environmental temperature is high, the amount of water to be supplied is set to be small, so that the water is not retained in the deodorizing filter despite the middle of the drying time, and the environmental temperature is low. In this case, it is possible to suppress the supply of water in a state where the amount of supplied water is not set and the deodorizing filter is not dried.
Therefore, according to such a configuration, water can be supplied after the deodorizing filter is in a dry state, and water discharged without being held by the filter can be reduced. Further, the deodorizing filter can be kept in a state of holding water until a predetermined drying time elapses.

  Further, the fifth aspect includes a device main body, a suction unit that sucks air outside the device main body, a deodorization filter through which the air sucked by the suction unit passes, and water to the deodorization filter. A water supply unit that supplies water, a temperature detection unit that detects environmental temperature, a water supply unit that instructs the water supply unit to supply a predetermined amount of water to the deodorizing filter, and a temperature detection unit Based on the detection, a drying time setting means for setting a drying time for drying the deodorizing filter supplied with the water in the supply water amount, and the water supply means supplies the water in the supply water amount to the deodorizing filter. And a deodorizing means for deodorizing the air by operating the suction part and supplying the water to the deodorizing filter again after the drying time has elapsed. It is.

  According to such a configuration, the drying time setting unit sets the time until the water supplied by the water supply unit dries based on the detection of the temperature detection unit. Then, after the supply amount of water is supplied to the deodorization filter, the suction unit is operated until the drying time elapses, and air is passed through the deodorization filter holding the water to perform deodorization, and the water supplied to the deodorization filter Dry. Since the deodorizing filter is in a dry state after the drying time has elapsed, water is again supplied to the deodorizing filter when the deodorizing filter continues to deodorize air. That is, in the drying time setting means, the time required for the deodorizing filter supplied with the predetermined amount of water to be dried is set as the drying time.

  Therefore, the water supply means can supply water to the deodorizing filter after the drying time has elapsed and the deodorizing filter is in a dry state. As a result, more water is held in the deodorizing filter than in the case where water is supplied in a state where the deodorizing filter is not dried, and the amount of water discharged without being held in the filter can be reduced.

  Further, the sixth aspect includes an apparatus main body, a suction part that sucks air outside the apparatus main body, a deodorization filter through which the air sucked by the suction part passes, and water to the deodorization filter. A water supply unit to supply, a temperature detection unit for detecting an environmental temperature, a water supply amount setting means for setting the supply water amount of the water to be supplied to the deodorizing filter based on the detection of the temperature detection unit, and the water supply unit Water supply means for instructing the supply of the supply water amount to the deodorization filter, and after the water supply means supplies the water of the supply water amount to the deodorization filter, the suction unit is operated to A toilet seat device comprising: deodorizing means for performing deodorization and supplying the water to the deodorization filter again after a predetermined drying time has elapsed.

  According to such a configuration, the water supply amount setting means sets the amount of water supplied by the water supply means based on the detection of the temperature detection unit. Then, after the supply amount of water is supplied to the deodorizing filter, the suction unit is operated until a predetermined drying time elapses, and air is passed through the deodorizing filter holding the water to deodorize the deodorizing filter. Dry the supplied water. When the predetermined drying time has elapsed, the deodorizing filter is in a dry state. Therefore, when air is continuously deodorized by the deodorizing filter, water is again supplied to the deodorizing filter. That is, in the water supply amount setting means, the amount of water in which the deodorizing filter is dried during a predetermined drying time is set as the supply water amount.

  Therefore, the water supply means can supply water after the deodorizing filter is dry, and more water is supplied to the deodorizing filter than when water is supplied when the deodorizing filter is not dry. Water that is retained and discharged without being retained by the deodorizing filter can be reduced.

  According to the present invention, there is provided a toilet seat apparatus capable of keeping the deodorizing filter holding water while deodorizing with the deodorizing filter and reducing electrolyzed water discharged without being held by the deodorizing filter. can do.

<First Embodiment>
<Outline of toilet seat device>
Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic perspective view showing a toilet room in which a toilet seat device according to an embodiment of the present invention is installed.
FIG. 2 is a schematic perspective view showing the toilet seat device according to the present embodiment.

  As shown in FIG. 1, a flush toilet 2 is installed inside the toilet room 100. The toilet 2 is provided with a toilet seat device 1 (device main body). The toilet seat device 1 according to the present embodiment includes a toilet seat (not shown), a toilet lid 4, and a functional unit 6. For example, when the user operates the operation unit 74 installed on the wall surface of the toilet room 100, the user can open and close the toilet lid 4 and operate various functions of the function unit 6.

  As shown in FIG. 2, the functional unit 6 includes a case plate 8, a case cover 10, a cleaning water supply device 12 (see FIG. 3), a human body detection sensor 13, a cleaning nozzle 14, and a deodorizing device 16. And a temperature detection unit 17 (see FIG. 3) and a control unit 18. The toilet seat (not shown) and the toilet lid 4 are pivotally supported with respect to the case cover 10 so as to be freely opened and closed. The case plate 8 is provided behind the bowl portion 20 of the toilet 2 when viewed from the front (front) of the toilet 2. The case plate 8 is provided with a cleaning water supply device 12, a cleaning nozzle 14, a deodorizing device 16, and a control unit 18. The case cover 10 covers the cleaning water supply device 12, the cleaning nozzle 14, the deodorizing device 16, and the control unit 18 and is fixed to the case plate 8.

  The human body detection sensor 13 is a pyroelectric sensor using an infrared signal, for example, and detects a person who has entered the toilet room 100. The human body detection sensor 13 may be a microwave sensor such as a Doppler sensor. When a sensor using the microwave Doppler effect or a sensor for detecting a detected object based on the amplitude (intensity) of the microwave transmitted and reflected is used as the human body detection sensor 13, human body detection is performed. The sensor 13 can detect the presence of the user through the door of the toilet room 100. That is, the human body detection sensor 13 can detect the user before entering the toilet room 100. Moreover, the temperature detection part 17 detects the environmental temperature of the space where the toilet seat apparatus 1 is installed. Here, environmental temperature is the temperature of the air in the toilet room 100 in which the toilet seat apparatus 1 is installed, for example. However, the environmental temperature is not limited to this, and may be, for example, the temperature of air sucked from an air inlet 21 described later or the temperature of water supplied to the toilet seat device 1.

  The deodorizing device 16 is installed on the rear left side of the case plate 8 when viewed from the front of the toilet 2. As indicated by an arrow A <b> 28 illustrated in FIG. 2, the deodorizing device 16 sucks air in the toilet room 100 from an air inlet portion 21 provided on the left side of the case cover 10 when viewed from the front of the toilet 2. The air in the toilet room 100 mainly refers to the air outside the toilet 2 (air other than the bowl portion 20). The malodorous component contained in the air sucked from the air inlet 21 is collected or decomposed by the deodorizing device 16.

  In the specification of the present application, the upper side is “upward” when viewed from the user sitting on the toilet 2 in the normal use state, and the lower side is “downward” when viewed from the user sitting on the toilet 2 in the normal use state. Further, the front is “front” when viewed from the user sitting on the toilet 2 in the normal use state, and the rear is “rear” when viewed from the user sitting on the toilet 2 in the normal use state. Alternatively, as viewed from the user standing in front of the urinal 2 facing the toilet 2, the front side is “front” and viewed from the user standing in front of the urinal 2 facing the toilet 2. The back side is “back”. Also, the right side is “right” when viewed from the user standing in front of the toilet 2 facing the toilet 2, and the user standing in front of the toilet 2 facing the toilet 2. The left side is the “left side”.

  The “bad odor component” in the present embodiment includes an ammonia component. This malodorous component is generated from the urine adhering portion when urine adheres to the floor or wall of the toilet room 100.

  As indicated by an arrow A29 shown in FIG. 2, the air in which malodorous components are collected or decomposed by the deodorizing device 16 is viewed from the exhaust port 22 provided on the left side of the case cover 10 when viewed from the front of the toilet 2. It is discharged into the toilet room 100.

  Since the exhaust port 22 is provided on the side surface of the case cover 10, air is not discharged to the front of the case cover 10. Therefore, it can suppress that the air discharged | emitted from the exhaust port part 22 hits a user directly. Thereby, the convenient toilet seat apparatus 1 can be provided. In addition, the installation form of the inlet part 21 and the exhaust port part 22 is not limited to the example shown in FIG. For example, the air inlet 21 may be provided on the rear surface (back surface) of the case cover 10. Alternatively, at least one of the intake port portion 21 and the exhaust port portion 22 may be provided on the right side surface.

  In the example shown in FIG. 2, the exhaust port 22 is provided on the front side of the intake port 21. Therefore, the exhaust port 22 can discharge air from which the malodorous components are collected or decomposed from the front side of the intake port 21. Therefore, the user is relatively easy to inhale air in which malodorous components are collected or decomposed. Therefore, it is possible to further suppress the user from feeling uncomfortable.

  The control unit 18 is a control circuit including an IC element, and electrically controls the operations of the cleaning water supply device 12, the human body detection sensor 13, the cleaning nozzle 14, the temperature detection unit 17, and the deodorizing device 16. For example, the control unit 18 controls the operation of the fan 46 (see FIG. 3). The control unit 18 is covered with a control unit cover (not shown) as a metal housing, for example.

<Method of generating functional water>
FIG. 3 is a block diagram illustrating the main configuration of the cleaning water supply device and the deodorization device of the present embodiment.
FIG. 4 is a schematic perspective view showing the deodorizing apparatus of this embodiment.
FIG. 5 is a schematic exploded view showing the deodorizing apparatus of this embodiment.
FIG. 6 is a schematic cross-sectional view illustrating a specific example of the electrolytic cell of this embodiment.

  As shown in FIG. 3, the washing water supply device 12 includes a flow path opening / closing valve 24, an instantaneous heating type heat exchanger 26, an electrolytic cell 28, an air release type vacuum breaker (VB) 30, and a washing nozzle. 14, a second flow path 34 leading to the deodorizing device 16, an electromagnetic pump 36, and a flow control / flow path switching valve 38. Note that the cleaning water supply device 12 does not necessarily have the heat exchanger 26. The water supplied from the outside is sent to the electrolytic cell 28 through the heat exchanger 26 when the flow path opening / closing valve 24 is opened.

  As shown in FIG. 6, the electrolytic cell 28 includes a first electrode 28 a and a second electrode 28 b. The first electrode 28a is, for example, an anode. The second electrode 28b is, for example, a cathode. The first electrode 28 a and the second electrode 28 b are provided inside the electrolytic cell 28. The electrolytic cell 28 can electrolyze tap water flowing in the space between the first electrode 28 a and the second electrode 28 b based on the energization control signal transmitted from the control unit 18. In other words, the water sent to the electrolytic cell 28 is electrolyzed inside the electrolytic cell 28.

The tap water contains chlorine ions (Cl ⁻ ). Chlorine ions are contained as salt (NaCl), calcium chloride (CaCl ₂ ) and the like in a water source (for example, groundwater, dam water, river water, etc.). Therefore, the reaction represented by Chemical Formula 1 occurs at the anode (for example, the first electrode 28a).

  Chlorine generated in Chemical Formula 1 is unlikely to exist as bubbles, and most of the chlorine dissolves in water. Therefore, for the chlorine generated in Chemical Formula 1, the reaction expressed in Chemical Formula 2 occurs.

  Thus, hypochlorous acid (HClO) is produced by electrolyzing chlorine ions. As a result, the water electrolyzed in the electrolytic cell 28 changes to a liquid containing hypochlorous acid (hereinafter referred to as “functional water”).

  The functional water generated by the electrolytic cell 28 flows to the first flow path 32 or the second flow path 34. The functional water that has flowed into the first flow path 32 is sent to the cleaning nozzle 14 by the electromagnetic pump 36. The cleaning nozzle 14 has a water discharge unit 15. For example, the water discharger 15 includes a butt cleaning water discharge hole 15a, a butt soft water discharge hole 15b, a bidet cleaning water discharge hole 15c, and a wide bidet cleaning water discharge hole 15d. However, the water discharge hole which the water discharge part 15 has is not limited to this. The functional water sent to the cleaning nozzle 14 is discharged from the water discharge unit 15. The functional water discharged from the water discharge unit 15 is used for cleaning the outer surface of the cleaning nozzle 14, that is, for trunk cleaning.

  Between the electromagnetic pump 36 and the cleaning nozzle 14, a flow control / flow path switching valve 38 is provided. By operating the flow control / flow path switching valve 38, the water discharge flow rate, water discharge angle, water discharge range, and the like of the functional water discharged from the washing nozzle 14 can be changed. Further, the functional water can be sent to the nozzle cleaning chamber (body cleaning section) 40 by operating the flow control / flow path switching valve 38. The nozzle cleaning chamber 40 has a water discharge unit 41. The nozzle cleaning chamber 40 performs cleaning of the outer surface of the cleaning nozzle 14, that is, body cleaning by discharging functional water from the water discharger 41.

<Deodorizing principle with deodorizing device>
The functional water that has flowed to the second flow path 34 is sent to the deodorizing device 16. As shown in FIGS. 3 to 5, the deodorization device 16 includes a dust collection filter 44, a fan 46 (suction unit), a deodorization filter 48, a spray unit 50 (water supply unit), a water receiving unit 52, And a filter case 72.

  The water receiver 52 has an intake port 42 and an exhaust port 54. The air inlet 42 is installed in the air inlet 21 of the case cover 10. The exhaust port 54 is installed in the exhaust port portion 22 of the case cover 10. The fan 46 is, for example, a resin sirocco fan. The fan 46 sucks air in the toilet room 100 from the air inlet 42 and discharges the sucked air from the air outlet 54 to the toilet room 100 by rotating a plurality of wings provided inside. The fan 46 is not limited to a sirocco fan. As described above, the fan 46 is a suction unit that sucks air outside the toilet seat device 1 from the air inlet 42 into the toilet seat device 1.

  As shown in FIG. 4, the dust collection filter 44 is installed inside the first slat 68. The dust collection filter 44 prevents dust and dirt in the sucked air from being sent to the fan 46. The dust collection filter 44 can be removed from the deodorizing device 16 by removing the first slat 68 from the case cover 10. Therefore, the dust collection filter 44 can be easily detached from the toilet seat device 1. Thereby, the dust collection filter 44 can be more easily cleaned. The dust collection filter 44 may be provided integrally with the first slat 68. In this case, the dust collection filter 44 and the first slat 68 can be removed from the case cover 10 at the same time. Alternatively, the dust collection filter 44 may be installed in the portion of the air inlet 42.

The deodorizing filter 48 has a porous structure. That is, the deodorizing filter 48 has a porous structure.
In the specification of the present application, the “porous structure” refers to a structure in which the density of the material is 1 gram / cubic centimeter (g / cm ³ ) and water of 0.5 milliliter (mL) or more per 1 g can be retained. . In other words, the “porous structure” in the specification of the present application refers to a structure in which a cube having a weight of 1 g and a cube having a side length of 1 cm can hold water of 0.5 milliliter (mL) or more. And

The material of the deodorizing filter 48 includes ceramic. More specifically, the material of the deodorizing filter 48 includes silica (SiO ₂ ) and alumina (Al ₂ O ₃ ). More specifically, the deodorizing filter 48 is a mixed sintered body of silica and alumina. The deodorizing filter 48 has a honeycomb structure. A specific example of the honeycomb structure of the deodorizing filter 48 will be described later. The deodorizing filter 48 is held in the filter case 72.

  Functional water is supplied to the deodorizing filter 48 by the spray unit 50. The deodorizing filter 48 is provided between the fan 46 and the exhaust port 54, that is, on the downstream side of the fan 46. In other words, the fan 46 is installed upstream of the deodorizing filter 48 to which functional water is supplied. Therefore, air containing moisture can be prevented from being sent from the deodorizing filter 48 to the fan 46. Therefore, it is possible to prevent the fan 46 from malfunctioning due to moisture.

  The air exhausted from the fan 46 passes through the deodorizing filter 48. Therefore, the air accumulated in the toilet seat device 1 before the fan 46 operates always passes through the deodorizing filter 48 and is discharged to the toilet room 100 after the malodorous components are collected. Therefore, when the fan 46 is operated, it is possible to prevent the air accumulated in the toilet seat device 1 from being discharged into the toilet room 100 without collecting or decomposing malodorous components.

  The deodorizing filter 48 can be freely taken out from the exhaust port 54 by a user's operation. More specifically, the deodorizing filter 48 can be taken out while being held in the filter case 72. The user can remove the deodorizing filter 48 from the exhaust port 54 by removing the deodorizing filter 48 from the filter case 72. This improves the cleanability of the deodorizing filter 48.

  The spray unit 50 has an electromagnetic valve and is provided above the deodorizing filter 48. When the spray unit 50 is opened by the control unit 18, the functional water is sprayed from above the deodorization filter 48 toward the deodorization filter 48 for about 3 seconds to 5 seconds, for example. The functional water is sprayed while spreading in a conical shape with the spraying portion 50 at the top. The spread angle of the functional water sprayed from the spray unit 50 is about 110 degrees.

  When the functional water is sprayed toward the deodorizing filter 48, the deodorizing filter 48 holds the functional water. The diameter of the water sprayed from the spray part 50 is about 10 micrometers (micrometer) or more and 1000 micrometers or less, for example. Therefore, the functional water sprayed from the spray unit 50 penetrates into the material of the deodorizing filter 48. In the present specification, “penetration” includes not only that the liquid penetrates the material but also that the liquid is held in the pores of the porous structure.

  When the fan 46 operates, the air in the toilet room 100 sucked from the air inlet 42 passes through the deodorizing filter 48. Here, when air passes through the deodorizing filter 48 in a state where the deodorizing filter 48 holds the functional water, malodorous components contained in the air are taken into the functional water. The malodorous component taken in the functional water is decomposed by the following formula by hypochlorous acid contained in the functional water.

As shown in Chemical Formula 3, ammonia (NH ₃ ) changes to monochloramine (NH ₂ Cl) and water (H ₂ O) by reacting with hypochlorous acid (HClO). The smell of monochloramine is the same odor as chlorine. The user can feel cleanliness due to the smell of monochloramine. The malodorous component remaining without being decomposed is collected in functional water. Therefore, it can suppress that the malodorous component which remained without being decomposed | disassembled returns to air. As a result, bad odor components are removed from the air that has passed through the deodorizing filter 48.

  The air from which the malodorous component is removed is discharged from the exhaust port 54 to the toilet room 100. As described above, the deodorizing device 16 can collect or decompose malodorous components that are always present in the toilet room 100. Therefore, every time the user enters the toilet room 100, the user does not inhale the odor due to the malodorous component that always exists in the toilet room 100, and the user can use the toilet room 100 comfortably.

  According to this embodiment, since the deodorizing filter 48 has a porous structure, it is easy to hold functional water. Therefore, the toilet seat apparatus 1 according to the present embodiment can ensure higher deodorization performance. Moreover, since functional water is a liquid containing hypochlorous acid, ammonia and trimethylamine can be decomposed by hypochlorous acid. Moreover, since the material of the deodorizing filter 48 contains ceramic, the deodorizing filter 48 has a certain hardness and can suppress deformation due to aging. Moreover, since the deodorizing filter 48 is a mixed sintered body of silica and alumina, it can suppress corrosion caused by functional water and can be used for a longer period. Furthermore, since the deodorizing filter 48 has a honeycomb structure, the contact area between the air in the toilet room 100 sucked from the air inlet 42 and the functional water is wider. Therefore, the decomposition performance of malodorous components such as ammonia can be improved.

  As described above with reference to FIGS. 1 and 2, the source of malodorous components in the embodiment is urine adhering to the floor or wall of the toilet room 100, and the source of malodorous components in the bowl portion 20 of the toilet 2 is Different. Therefore, when the air inlet 42 of the deodorizing device 16 is installed in the air inlet portion 21 provided on the side surface or the rear surface of the case cover 10, the deodorizing device 16 easily performs deodorization.

  The air discharged from the fan 46 passes through the deodorizing filter 48 from the upper side to the lower side of the deodorizing filter 48. Thereby, the accumulated matter such as scale and dust accumulated in the deodorizing filter 48 can be removed to the water receiving portion 52 by the air exhausted from the fan 46 and the weight of the accumulated matter itself. For this reason, it is difficult for accumulated matter to accumulate in the deodorizing filter 48.

  Note that the air discharged from the fan 46 may pass through the deodorizing filter 48 from below to above the deodorizing filter 48. In this case, scale, dust and the like stay in the lower part of the deodorizing filter 48 (the upwind portion of the deodorizing filter 48). On the other hand, the functional water is sprayed from above the deodorizing filter 48 toward the deodorizing filter 48. As a result, the accumulated matter such as scale and dust accumulated in the lower part of the deodorizing filter 48 can be dropped into the water receiving part 52 by the functional water sprayed from the spraying part 50.

  As shown in FIGS. 4 and 5, the water receiver 52 has a drain port 56 that opens toward the case plate 8. The bottom surface of the water receiving portion 52 is inclined toward the drain port 56. Thereby, the functional water that has flowed to the water receiving portion 52 flows toward the drain port 56 without collecting on the bottom surface of the water receiving portion 52.

FIG. 8 is a schematic plan view illustrating a specific example of a deodorizing filter and a filter case.
FIG. 9 is a schematic plan view illustrating a specific example of the honeycomb structure of the deodorizing filter of the present embodiment.

FIG. 8A is a schematic plan view showing the filter case when viewed in the direction of arrow A31 shown in FIG. FIG. 8B is a schematic plan view illustrating the upper deodorizing filter when viewed in the direction of the arrow A31 illustrated in FIG. FIG. 8C is a schematic plan view showing the lower deodorizing filter when viewed in the direction of the arrow A31 shown in FIG. FIG. 8D is a schematic side view when the deodorizing filter in a state where the upper deodorizing filter and the lower deodorizing filter are overlapped is viewed from the direction orthogonal to the arrow A31 illustrated in FIG.
That is, FIG. 8A to FIG. 8C are schematic plan views illustrating specific examples of the upper deodorizing filter, the lower deodorizing filter, and the filter case when viewed from the upper side to the lower side. FIG. 8D is a schematic side view illustrating a specific example of the deodorizing filter in a state where the upper deodorizing filter and the lower deodorizing filter are overlapped when viewed from the front to the rear.
FIG. 9A is a schematic plan view showing a structure in which holes of square pillars are arranged. FIG. 9B is a schematic plan view showing a structure in which triangular prism holes are arranged. FIG. 9C is a schematic plan view showing a structure in which hexagonal column holes are arranged. FIG. 9A to FIG. 9C are schematic plan views in which the deodorizing filter is viewed in an enlarged manner when viewed in the direction of the arrow A31 illustrated in FIG.

  As shown in FIG. 7, the deodorizing filter 48 is held by the filter case 72. As shown in FIG. 8D, the deodorizing filter 48 is configured by stacking an upper deodorizing filter 49a shown in FIG. 8B and a lower deodorizing filter 49b shown in FIG. 8C. . Further, as shown in FIGS. 8A to 8C, the first direction of the portion of the filter case 72 that holds the deodorizing filter 48 (lateral direction in FIG. 8A). Is longer than the length D3 in the first direction of the upper deodorizing filter 49a and the length D5 in the first direction of the lower deodorizing filter 49b. The length D2 in the second direction (vertical direction in FIG. 8A) of the portion of the filter case 72 where the deodorizing filter 48 is held is the length D4 in the second direction of the upper deodorizing filter 49a. And the length D6 of the lower deodorizing filter 49b in the second direction is longer. That is, there is a gap between the deodorizing filter 48 and the filter case 72 in a state where the deodorizing filter 48 in which the upper deodorizing filter 49 a and the lower deodorizing filter 49 b are stacked is held by the filter case 72.

  According to this, it is possible to disperse the external force applied to the deodorizing filter 48 and to prevent the deodorizing filter 48 from being damaged even when the material of the deodorizing filter 48 is ceramic. For example, an external force may be applied to the deodorizing filter 48 when the deodorizing filter 48 is attached to the filter case 72 or when the deodorizing filter 48 is removed from the filter case 72. Even in this case, since there is a gap between the deodorizing filter 48 and the filter case 72, the external force applied to the deodorizing filter 48 can be dispersed and the deodorizing filter 48 can be prevented from being damaged.

  The upper deodorizing filter 49a and the lower deodorizing filter 49b have a honeycomb structure. In the specific examples shown in FIG. 8B, FIG. 8C, and FIG. 9A, the upper deodorizing filter 49a and the lower deodorizing filter 49b have a structure in which square pillar holes 48a are arranged. As in the specific example shown in FIG. 9B, the upper deodorizing filter 49a and the lower deodorizing filter 49b of the present embodiment may have a structure in which triangular holes 48b are arranged. Alternatively, as in the specific example shown in FIG. 9C, the upper deodorizing filter 49a and the lower deodorizing filter 49b of the present embodiment may have a structure in which hexagonal column holes 48c are arranged.

Thus, in the present specification, the “honeycomb structure” is not limited to a structure in which hexagonal column holes are arranged, but refers to a structure in which three-dimensional figures such as triangular column holes and square column holes are arranged. .
FIGS. 9A to 9C show three-dimensional figures that the honeycomb structures of the upper deodorizing filter 49a and the lower deodorizing filter 49b have when viewed from the upper side to the lower side.

  The axis of the three-dimensional figure which the honeycomb structure of the upper side deodorizing filter 49a and the lower side deodorizing filter 49b has is parallel to an up-down direction. In the specific example shown in FIG. 9A, the axis of the solid figure of the honeycomb structure of the upper deodorizing filter 49a and the lower deodorizing filter 49b is the axis of the hole of the quadrangular prism, and is shown in FIG. 9B. In the specific example, it is the axis of the triangular prism hole, and in the specific example shown in FIG. 9C, it is the axis of the hexagonal column hole.

  According to this, water is sufficiently distributed in the vertical direction of the upper deodorizing filter 49a and the lower deodorizing filter 49b. Therefore, substantially the entire upper deodorizing filter 49a and lower deodorizing filter 49b are in a state of holding water. Thereby, the toilet seat apparatus 1 concerning this embodiment can ensure higher deodorizing performance.

  In addition, in the honeycomb structure of the lower deodorizing filter 49b, the holes 48a of each square pillar are larger than the honeycomb structure of the upper deodorizing filter 49a. That is, the honeycomb structure of the lower filter 49b is rougher than the honeycomb structure of the upper deodorizing filter 49a.

  Since the upper deodorizing filter 49a has a fine honeycomb structure, the water supplied to the upper deodorizing filter 49a may block the holes of the quadrangular columns due to surface tension. If it does so, since air will not pass the hole of the square pillar of the upper side deodorizing filter 49a, deodorizing performance will fall. In order to prevent such blocking of the honeycomb structure of the upper deodorizing filter 49a due to the surface tension of water, in this specific example, the lower deodorizing filter 48b having a honeycomb structure rougher than the upper deodorizing filter 49a is replaced with the upper deodorizing filter 49a. It is stacked below.

  When one side of the honeycomb structure of the lower deodorizing filter 49b, which forms a larger square pillar hole than the upper deodorizing filter 49a, comes into contact with the water blocking the square pillar hole of the upper deodorizing filter 49a, the side deodorizing is performed. The surface tension of the water blocking the holes of the quadrangular columns of the filter 49a is destroyed, and the blockage of the holes of the quadrangular columns of the upper deodorizing filter 49a can be eliminated.

  By doing in this way, since it can suppress that the hole of the square pillar of the upper side deodorizing filter 49a is obstruct | occluded with water, the toilet seat apparatus 1 concerning this embodiment can ensure higher deodorizing performance. .

Further, since the honeycomb structure of the lower deodorizing filter 49b is rougher than that of the upper deodorizing filter 49a, the water retention amount of the lower deodorizing filter 49b is smaller than the water retention amount of the upper deodorizing filter 49a. Therefore, in order to increase the water retention amount of the entire deodorizing filter 48, it is preferable to make the thickness D7 of the upper deodorizing filter 49a thicker than the thickness D8 of the lower deodorizing filter 49b, as shown in FIG. 8 (d). .
Thereby, since the volume of the upper side deodorizing filter 49a with much water retention amount can be enlarged, the water retention amount as the whole deodorization filter 48 can be increased.

<How to clean the deodorizing filter>
FIG. 10 is a schematic plan view showing the inside of the toilet seat device according to the present embodiment.
The cleaning of the deodorizing filter of the present embodiment will be described with reference to FIG.

  As described above with reference to FIGS. 3 to 6, the deodorizing apparatus 16 of the present embodiment collects or decomposes malodorous components contained in the air by allowing the air to pass through the deodorizing filter 48 holding functional water. Therefore, a substance that causes odor is adsorbed to the deodorizing filter 48. If the deodorizing filter 48 is not maintained, the deodorizing performance of the deodorizing filter 48 may not be ensured.

  On the other hand, the control unit 18 of the present embodiment executes control for performing the cleaning operation of the deodorizing filter 48. The control unit 18 supplies functional water that is equal to or greater than the maximum water retention amount of the deodorizing filter 48 to the deodorizing filter 48 during a non-use period of the user. The control unit 18 may supply the functional water to the deodorizing filter 48 a plurality of times during a predetermined time. In this case, the total amount of the plurality of times of supply may be equal to or greater than the water retention amount of the deodorizing filter 48. Alternatively, the amount of each of the multiple times of supply may be equal to or greater than the water retention amount of the deodorizing filter 48. The “predetermined time” is, for example, about 1 minute or more and 10 minutes or less. Details of the “non-use time zone” will be described later.

  The maximum water retention amount of the deodorizing filter 48 is about 20 mL. When cleaning the deodorizing filter 48, the spray unit 50 sprays about 100 mL or more and 150 mL or less of functional water toward the deodorizing filter 48. That is, the spray unit 50 can clean the deodorizing filter 48 by spraying water that is equal to or greater than the maximum water retention amount of the deodorizing filter 48. Thereby, the bad odor component which the functional water hold | maintained at the deodorizing filter 48 collected can be washed away before spraying of functional water.

  The functional water used for cleaning the deodorizing filter 48 flows to the water receiving portion 52 located below the deodorizing filter 48. The functional water that has flowed to the water receiver 52 is discharged from the drain 56 of the water receiver 52 and guided to the upper surface of the case plate 8.

  As shown in FIG. 10, ribs 58 are provided on the upper surface of the case plate 8. The rib 58 protrudes upward from the upper surface of the case plate 8 to form a discharge flow path 60. The discharge channel 60 discharges the water that has passed through the deodorizing filter 48. For example, the discharge channel 60 discharges the functional water that has washed the deodorizing filter 48. The discharge channel 60 has a bowl portion discharge hole 62. The bowl portion discharge hole 62 is provided adjacent to the position where the nozzle cleaning chamber 40 is installed. The bowl portion discharge hole 62 is provided in the front portion of the case plate 8. The rib 58 is provided in a linear shape, and guides the functional water discharged from the drain port 56 (see FIGS. 4 and 5) to the bowl portion discharge hole 62.

  The discharge channel 60 is inclined downward toward the front. Accordingly, as indicated by arrows A21 to A27 illustrated in FIG. 10, the functional water discharged from the drain outlet 56 flows forward through the discharge channel 60 according to gravity. Thereby, the functional water discharged from the drain port 56 can be more easily guided to the bowl portion discharge hole 62.

  The functional water guided to the bowl portion discharge hole 62 is discharged to the bowl portion 20 of the toilet 2. Thus, the functional water used for cleaning the deodorizing filter 48 and collecting the malodorous component is discharged to the bowl portion 20. In the bowl part 20, washing with water is frequently performed. Thereby, it can suppress that the site | part to which the functional water adheres drys and generate | occur | produces an odor, and can suppress that a user feels discomfort.

  The bowl portion discharge hole 62 is adjacent to the position where the nozzle cleaning chamber 40 is installed. Therefore, when the nozzle cleaning chamber 40 cleans the body of the cleaning nozzle 14, the functional water used for cleaning the body of the cleaning nozzle 14 flows through a part of the discharge channel 60 from the bowl part discharge hole 62 to the bowl part. It is discharged to 20. That is, the functional water used for cleaning the body of the cleaning nozzle 14 flows through a part of the discharge channel 60 through which the functional water discharged from the drain port 56 of the water receiving portion 52 flows. As a result, a part of the discharge flow path 60 and the bowl portion discharge hole 62 are cleaned with water that has been subjected to body cleaning of the cleaning nozzle 14. Thereby, it is possible to suppress the generation of odor from the discharge flow path 60 and the bowl portion discharge hole 62 after the functional water that has collected the malodorous component is dried, and to suppress the user from feeling uncomfortable. it can.

  Moreover, the washing nozzle 14 wash | cleans the part of the water discharging part 15 by discharging functional water from all the water discharge holes which the water discharging part 15 has in the state accommodated in the space between the case plate 8 and the case cover 10. Can (self-cleaning). At this time, the water discharge portion 15 of the cleaning nozzle 14 is accommodated in the nozzle cleaning chamber 40. Therefore, the functional water discharged from the water discharge unit 15 is reflected by the inner wall of the nozzle cleaning chamber 40 and is applied to the water discharge unit 15. Thereby, the portion of the water discharger 15 is also cleaned by the functional water reflected by the inner wall of the nozzle cleaning chamber 40.

  The functional water used for self-cleaning flows through a part of the discharge channel 60 and is discharged from the bowl portion discharge hole 62 to the bowl portion 20. That is, the functional water used for self-cleaning flows through a part of the discharge channel 60 through which the functional water discharged from the drain 56 of the water receiving portion 52 flows. As a result, a part of the discharge flow path 60 and the bowl portion discharge hole 62 are washed with the self-cleaned water. Thereby, it is possible to suppress the generation of odor from the discharge flow path 60 and the bowl portion discharge hole 62 after the functional water that has collected the malodorous component is dried, and to suppress the user from feeling uncomfortable. it can.

  Further, since the bowl portion discharge hole 62 is adjacent to the position where the nozzle cleaning chamber 40 is installed, the discharge position of the functional water used for cleaning the deodorizing filter 48 to the bowl portion 20 is the self-cleaning and cleaning nozzle. 14 is adjacent to the discharge position of the functional water used for the body cleaning to the bowl portion 20. Thereby, when the functional water used for cleaning the deodorizing filter 48 is discharged to the bowl portion 20, the user can be prevented from recognizing that the toilet seat device 1 is out of order.

<Specific example of operation of toilet seat device>
Next, a specific example of the operation of the toilet seat device 1 according to the present embodiment will be described with reference to the drawings.
FIG. 11 is a table illustrating a method for determining the usage frequency.

  The control unit 18 of the present embodiment divides one day (24 hours) every 45 minutes to form 32 units, and stores the presence or absence of human body detection by the human body detection sensor 13. In the table shown in FIG. 11, eight units out of 32 units are taken as an example. In the table shown in FIG. 11, the symbol “◯” is described when the human body detection sensor 13 detects a human body. On the other hand, when the human body detection sensor 13 does not detect a human body, no symbol is described (no symbol).

  The control unit 18 totals the number of times that the human body detection sensor 13 detects the human body (the number of times the user has used the toilet room 100) over two days in two units (90 minutes) adjacent to each other. When the total number of times in 90 minutes is 0 (zero), the control unit 18 sets the use frequency that the user is in the “non-use time zone” of the toilet room 100. When the total number of times in 90 minutes is 1 or more and less than 4, the control unit 18 sets the use frequency that the user is in the “less time zone” of the toilet room 100. When the total number of times in 90 minutes is 4 or more, the control unit 18 sets the use frequency that the user is in the “use time zone” of the toilet room 100.

  For example, in the two units (90 minutes) surrounded by the thick frame line shown in FIG. 11, the total number of times the human body detection sensor 13 detects the human body over 8 days is “3”. Therefore, the control unit 18 sets the usage frequency of the two units surrounded by the thick frame line illustrated in FIG.

<Description of deodorizing operation>
FIG. 12 is a flowchart showing a specific example of the deodorizing operation in the control unit 18 according to the present embodiment. FIG. 13 is a timing chart illustrating a specific example of operation when the temperature in the toilet room 100 is less than 10 degrees in the control unit 18 according to the present embodiment. FIG. 14 is a timing chart illustrating a specific example of operation when the temperature in the toilet room 100 is 10 degrees or more and less than 30 degrees in the control unit 18 according to the present embodiment. FIG. 15 is a timing chart illustrating a specific example of operation when the temperature in the toilet room 100 is 30 degrees or higher in the control unit 18 according to the present embodiment.

<Description of flowchart>
Control executed by the control unit 18 of this specific example will be described with reference to FIG. Note that FIG. 12 is a flowchart for explaining the deodorizing operation executed by the control unit 18, so that storage processing for presence / absence of human body detection by the human body detection sensor 13, processing for setting use frequency, and use by the cleaning nozzle 15 The local cleaning process of the person is omitted.

  When the toilet seat device 1 and the control unit 18 are turned on, the control unit 18 repeatedly executes the processes of steps S0 to S11 in FIG. 12 until the power is turned off. As shown in FIG. 12, the control unit 18 starts operation from step S0. First, in step S <b> 1, the control unit 18 determines whether the current time is, for example, 67.5 minutes before the “use time zone” or the “use time zone”. If the current time is either 67.5 minutes before the “use time zone” or the “use time zone”, the process proceeds to step S2, and if not, step S1 is repeated. .

  That is, the control unit 18 performs the deodorizing operation to execute the water supply unit 82, the drying time setting unit 80, and the deodorizing unit 84, which will be described later, from 67.5 minutes before 1.5 hours before the “use time zone”. The deodorizing operation is continued until the “use time period” elapses. The deodorizing operation is stopped in other time zones.

  In this way, by performing the deodorizing operation from 67.5 minutes before the usage frequency becomes the “use time zone”, before the time zone when the user is more likely to enter the toilet room 100, It is possible to remove the odor that is always present in the toilet room 100. Therefore, it is possible to prevent the user from feeling uncomfortable by sucking the odor that is always present in the toilet room 100.

  In this specific example, it has been described that the control unit 18 performs the deodorizing operation 67.5 minutes before the usage frequency becomes the “usage time zone”, but the time for starting the deodorizing operation is limited to this. As long as it is possible to remove the odor that is always present in the toilet room 100 before the time period when the usage frequency is high, the time for starting the deodorizing operation can be changed as appropriate.

  When the deodorizing operation is started in step S1, the control unit 18 proceeds to step S2. In step S2, the control unit 18 detects the room temperature T, which is the temperature of the air in the toilet room 100, as the environmental temperature based on the output of the temperature detection unit 17.

  Next, the control unit 18 selects and executes any one of steps S3 to S5 based on the room temperature T detected in step S2. In steps S3 to S5, a drying time required for drying the deodorizing filter 48 to which functional water of a predetermined supply water amount is supplied in step S6 described later is set.

  Specifically, when the room temperature T is 30 degrees or more, the control unit 18 executes step S3 and sets the drying time to 45 minutes. When the room temperature T is not less than 10 degrees and less than 30 degrees, the control unit 18 executes step S4 and sets the drying time to 67.5 minutes. When the room temperature T is less than 10 degrees, the control unit 18 executes step S5 and sets the drying time to 90 minutes.

  After the drying time is set in the drying time setting means 80, the control unit 18 executes step S6, and supplies functional water from the spray unit 50 to the deodorizing filter 48. At this time, the spray unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorizing filter 48 for, for example, about 3 seconds to 5 seconds. Thereby, the deodorizing filter 48 will be in the state holding the functional water of the maximum water retention amount (about 20 mL).

  Therefore, in the control unit 18 of this specific example, step S6 is the water supply means 82 that instructs the spray unit 50 to supply the predetermined amount of functional water to the deodorizing filter 48. The amount of functional water supplied from the spray unit 50 to the deodorizing filter 48 in the water supply unit 82 is constant and does not change according to the room temperature T detected by the temperature detection unit 17.

  In addition, in the control part 18 of this example shown in FIG. 12, the water supply means 82 shown in step S6 is executed after the drying time setting means 80 shown in steps S3 to S5. The operation of the control unit 18 is not limited to this. For example, the water supply unit 82 may be performed before detecting the room temperature T in step S2, or before the steps S3 to S5 which are drying time setting units. You may go to

  Subsequently, after supplying the functional water to the deodorizing filter 48 in step S6, the control unit 18 executes the deodorizing means 84 shown in steps S7 to S10. Specifically, first, in step S <b> 7, the execution of the water supply unit 82 is prohibited so that the functional water is not supplied from the spray unit 50. Thereby, functional water is not newly supplied to the deodorization filter 48 until the prohibition of the water supply means 82 is canceled in step S10 described later after the water supply means is executed in step S6. I have to.

  And the control part 18 performs step S8, and operates the fan 46. FIG. Thereby, since the air sucked from the air inlet 21 by the fan 46 passes through the deodorizing filter 48 in a state where the functional water is retained, the malodorous component contained in the air is collected or decomposed by the deodorizing filter 48.

  In step S8, the control unit 18 starts a timer (not shown). In subsequent step S9, the control unit 18 confirms whether or not the drying time set in steps S3 to S5 has elapsed from the value of the timer. The controller 18 repeats step S9 if the drying time has not elapsed, and proceeds to step S10 if the drying time has elapsed. In step S10, the prohibition of the water supply means 82 is canceled. Therefore, functional water can be supplied from the spray unit 50. At the same time, the fan 46 is stopped.

Since the execution of the water supply means 82 is prohibited until the prohibition of the functional water supply is canceled in step S10 after the functional water supply from the spray unit 50 is stopped in step S7, the deodorizing filter 48 is newly provided. Is not supplied with functional water.
Therefore, until the drying time elapses, the air sucked by the fan 46 is deodorized by the deodorizing filter 48 holding the functional water supplied by the water supply means 82 in step S6, and the step after the drying time elapses. When S10 is executed, the functional water supplied in step S6 is evaporated and the deodorizing filter 48 is in a dry state.

  As described above, in the control unit 18 of this specific example, steps S3 to S5 are performed to dry the deodorizing filter 48 to which the functional water of the supply water amount determined in advance based on the detection of the temperature detection unit 17 is supplied. A drying time setting means 80 for setting the time is provided. Further, in steps S7 to S10, after the water supply means 82 is executed in step S6, the fan 46 is operated to deodorize the air, and the execution of the water supply means 82 is prohibited until the drying time elapses. Deodorizing means 84 for drying the filter 48 is provided. In the present specification, “drying” of the deodorizing filter 48 refers to a state in which the weight of the deodorizing filter 48 that has absorbed or retained water has returned to the weight of the deodorizing filter 48 before absorbing or retaining water. Shall.

  When step S10 is executed, the control unit 18 ends the series of deodorization control processes in step S11. When the power is continuously turned on, the control unit 18 returns to step S0 and repeats the processes of steps S0 to S11 again.

<Explanation of timing chart>
Next, the state of the fan 46, the spray unit 50, and the deodorizing filter 48 in the deodorizing operation executed by the control unit 18 of this specific example shown in FIG. 12 will be described with reference to timing chart diagrams shown in FIGS. explain.
FIGS. 13 to 15 show states when the room temperature T detected by the temperature detector 17 is less than 10 degrees, when the temperature is 10 degrees or more and less than 30 degrees, and when the temperature is 30 degrees or more. .

  First, the case where the room temperature T is less than 10 degrees will be described with reference to FIG. In addition, in operation | movement of the control part 18 of this example shown in FIG. 13, 8 days or more have passed since the user used the toilet room 100. FIG.

  As shown in FIG. 13, the control unit 18 of this specific example satisfies the condition of step S1 shown in FIG. Therefore, the deodorization operation | movement after step S2 is performed. For this reason, the drying time setting means 80 and the water supply means 82 are executed at the timing t1 shown in FIG. Water is sprayed toward the deodorizing filter 48. Thus, the deodorizing filter 48 holds the maximum amount of functional water. In FIG. 13, since the room temperature T is less than 10 degrees, the drying time setting means 80 selects and executes step S5, and the drying time is set to 90 minutes.

  After the functional water is supplied to the deodorizing filter 48 at the timing t1, the deodorizing unit 84 is executed over the timings t1 to t2. Therefore, the fan 46 starts to operate, and the air sucked from the air inlet 21 passes through the deodorizing filter 48 in a state in which the functional water is retained. Therefore, the malodorous component contained in the air is collected by the deodorizing filter 48. Disassembled.

While the deodorizing unit 84 is being executed, the supply of functional water from the spray unit 50 is prohibited, so that no new functional water is supplied to the deodorizing filter 48. Therefore, the deodorizing filter 48 is gradually dried over time from the timing t1, and is in a dry state at the timing t2 when the drying time of 90 minutes has elapsed.
On the other hand, although the deodorizing filter 48 is gradually dried between the timings t1 and t2, since the functional water is retained, the malodorous components contained in the air passing through the deodorizing filter 48 are collected or decomposed. Can do.

  When the drying time has elapsed at the timing t2 shown in FIG. 13, step S10 shown in FIG. 12 is executed, and the prohibition of the water supply means 82 is released. Further, the operation of the fan 46 is stopped. Then, step S11 is performed and a series of deodorizing operation | movement shown in FIG. 12 is complete | finished.

  Since the control unit 18 of this specific example continues to operate after the timing t2, the control unit 18 repeats the execution of steps S0 to S11 shown in FIG. Therefore, step S1 is executed again at timing t2. Since the usage frequency at the timing t2 is “time zone to be used”, the condition of Step S1 is satisfied, and the control unit 18 executes the deodorizing operation after Step S2 of FIG.

  Thereby, at the timing t2, the drying time setting means 80, the water supply means 82, and the deodorizing means 84 are executed.

At timing t2, when the water supply means 82 is executed, since the drying time at timings t1 to t2 has elapsed, the deodorizing filter 48 is in a dry state. Therefore, functional water is supplied in the same state as when functional water is supplied at timing t1. That is, at the timing t2, the amount of functional water supplied from the spray unit 50 and held in the deodorizing filter 48 and the amount of functional water discharged from the drain port 52 are equal to the timing t1.
On the other hand, when the functional water is newly supplied in a state where the deodorizing filter 48 holds the functional water, compared with the case where the functional water is supplied in a state where the deodorizing filter 48 is dried, the drainage port 52 The amount of functional water drained increases.

  As described above, in the deodorizing operation performed by the control unit 18 of this specific example, the deodorizing unit 84 prohibits the execution of the water supplying unit 82 until the drying time elapses. When executed, the water supply means 82 is not executed until the drying time has elapsed. For this reason, the water supply means 82 can supply functional water to the deodorizing filter 48 after the drying time has elapsed and the deodorizing filter 48 is in a dry state. As a result, more functional water is retained in the deodorizing filter 48 than in the case where functional water is supplied in a state where the deodorizing filter 48 is not dried, and is discharged from the drain port 52 without being retained by the deodorizing filter 48. Functional water can be reduced.

  In addition, since functional water can be supplied again to the deodorizing filter 48 after the drying time has elapsed, the functional water is supplied again if the deodorizing operation is still in progress, so that the deodorizing filter 48 maintains the functional water. The malodorous component contained in the air sucked by the fan 46 can be repaired or decomposed and deodorized.

  Although the operation of the control unit 18 continues after the execution of the deodorizing means 84 is finished at the timing t3, the condition of step S1 shown in FIG. 12 is not satisfied over the timing t3 to t4, and therefore the deodorizing operation is performed. Not executed.

  Therefore, the deodorizing filter 48 is kept dry between the timings t3 and t4. Thus, when the deodorizing operation is not performed in the control unit 18 of this specific example, the deodorizing filter 48 is maintained in a dry state. Thereby, it is possible to suppress the growth of mold or bacteria on the deodorizing filter 48.

  Then, when the current time comes to timing t4, it is 67.5 minutes before the “time zone to be used”, so the condition of step S1 shown in FIG. 12 is satisfied, and the deodorizing operation is executed again. The deodorizing operation is repeatedly executed because the use frequency is “time zone to be used” at timing t5 when 90 minutes as the drying time has elapsed from timing t4.

  In FIG. 13, the case where the room temperature T in the toilet room 100 is less than 10 degrees has been described. However, when the room temperature T is greater than or equal to 10 degrees and less than 30 degrees, the fan 46, spray, The state of the unit 50 and the deodorizing filter 48 is as shown in FIG.

  Also in FIG. 14, when the usage frequency is 67.5 minutes before the “usable time zone” (timing t7), the condition of step S1 shown in FIG. 12 is satisfied, and therefore the deodorizing operation after step S2 is executed. The

  Even when the room temperature T is 10 degrees or more and less than 30 degrees, the amount of functional water supplied from the spray unit 50 by the water supply means 82 is the same, and therefore, compared with the case where the room temperature T is less than 10 degrees, the deodorizing filter. 48 takes less time to dry.

  In the control unit 18 of this specific example, since the drying time setting means 80 selects and executes step S4 according to the change in the room temperature T, the drying time is set to 67.5 minutes. Therefore, as shown in FIG. 14, when the room temperature T is 10 degrees or more and less than 30 degrees, the time (timing t <b> 7) from when the functional water is supplied from the spray unit 50 to when the drying time elapses and the fan stops. ˜t8) is shortened.

  Similarly, when the room temperature T in the toilet room 100 is 30 degrees or more, the drying time is set to 45 minutes because the drying time setting means 80 selects and executes step S3. Therefore, as shown in FIG. 15, when the room temperature T is 30 degrees or more, the time from when the functional water is supplied from the spray unit 50 to when the drying time elapses and the fan stops (timing t14 to t15). Is even shorter than the time (timing t7 to t8) when the room temperature T shown in FIG.

Since a predetermined amount of functional water is supplied from the spray unit 50 by the water supply means 82, the drying time required for the deodorizing filter 48 to dry is determined by the room temperature T in the toilet room 100. That is, if the amount of functional water supplied is the same, the time taken for the deodorizing filter 48 to dry is shorter when the room temperature T is higher than when the room temperature T is low.
Therefore, the drying time setting means 80 can set the drying time short according to the deodorizing filter 48 in which the time until drying changes according to the room temperature T by setting the drying time short as the room temperature T becomes high. .

  Accordingly, when the room temperature T is high, the drying time is set to be long, and the functional water is not held in the deodorizing filter 48 even though the deodorizing operation is being performed, and when the room temperature is low. It is possible to prevent the functional water from being supplied when the drying time is set short and the deodorizing filter 48 is not dried. Therefore, the functional water can be supplied after the deodorizing filter 48 is dried, and the functional water discharged without being held by the deodorizing filter 48 can be reduced. Further, during the deodorizing operation, the deodorizing filter 48 can be maintained in a state of holding the functional water, and the deodorizing effect of air by the deodorizing filter 48 can be obtained.

<Effects of First Embodiment>
As described above, in this specific example, the drying time setting unit 80 sets the time until the functional water supplied by the water supply unit 82 dries based on the detection of the temperature detection unit 17. Since the deodorizing means 84 prohibits the execution of the water supply means 82 until the drying time has elapsed, once the water supply means 82 is executed, the water supply means 82 is not executed until the drying time has elapsed. While the execution of the water supply means 82 is prohibited by the deodorizing means 84, the air sucked by the fan 46 passes through the deodorizing filter 48, so that malodorous components contained in the air outside the toilet seat device 1 are deodorized. . Moreover, the deodorizing filter 48 is gradually dried by passing the sucked air, and when the drying time elapses, the functional water supplied by the water supply means 82 becomes dry. That is, the drying time setting means 80 sets the time required for the deodorizing filter 48 to which the functional water having a predetermined supply water amount is supplied based on the detection of the temperature detection unit 17 to be in a dry state as the drying time.

For this reason, the water supply means 82 can supply functional water to the deodorizing filter 48 after the drying time has elapsed and the deodorizing filter 48 is in a dry state. Accordingly, more functional water is retained in the deodorizing filter 48 and less functional water is discharged without being retained by the deodorizing filter 48 than when functional water is supplied in a state where the deodorizing filter 48 is not dried. can do.
Moreover, since functional water can be supplied again to the deodorizing filter 48 after the drying time has elapsed, when deodorizing with the deodorizing filter is continued, the functional water is supplied again so that the deodorizing filter 48 retains the functional water. The odor contained in the air sucked from the fan 46 can be deodorized.

Moreover, since the functional water of the predetermined supply water quantity is supplied from the spray part 50, the drying time taken until the deodorizing filter 48 dries is decided by the room temperature T in the toilet room 100. That is, if the amount of functional water supplied is the same, the time taken for the deodorizing filter 48 to dry is shorter when the room temperature T is higher than when the room temperature T is low.
Therefore, the drying time setting means 80 can set the drying time according to the deodorizing filter 48 in which the time until drying is changed according to the room temperature T by setting the drying time shorter as the room temperature T becomes higher. .

Thereby, when the room temperature T is high, the drying time is set to be long, the water is not held in the deodorizing filter 48 even though the drying time is in the middle, and the room temperature T is low Therefore, it is possible to prevent the functional water from being supplied in a state where the drying time is set short and the deodorizing filter 48 is not dried.
Therefore, according to such a configuration, the functional water can be supplied after the deodorizing filter 48 is dried, and the functional water discharged without being held by the deodorizing filter 48 can be reduced. Moreover, until the set drying time elapses, the deodorizing filter 48 can be kept in a state of retaining functional water.

Second Embodiment
Subsequently, the control unit 18 according to the second embodiment of the present invention will be described with reference to FIGS. 16 to 18.

FIG. 16 is a flowchart showing a specific example of the deodorizing operation in the control unit 18 according to the second embodiment.

FIG. 18B is a timing chart illustrating a specific example of the operation when the temperature in the toilet room 100 is 30 degrees or higher in the control unit 18 according to the second embodiment.

<Description of flowchart>
Control executed by the control unit 18 according to the second embodiment will be described with reference to FIG. Since FIG. 16 is a flowchart for explaining the deodorizing operation executed by the control unit 18, a storage process of presence / absence of human body detection by the human body detection sensor 13, a setting process of use frequency, and a use by the cleaning nozzle 15 The local cleaning process of the person is omitted.

  As shown in FIG. 16, the control unit 18 starts operation from step S20. As in the first embodiment, in step S21, the control unit 18 determines whether the current time is 67.5 minutes before the “use time zone” or the “use time zone”. If the current time is either 67.5 minutes before the “use time zone” or the “use time zone”, the process proceeds to step S22; otherwise, step S21 is repeated. .

  And if the conditions of step S21 are satisfy | filled, it will progress to step S22 and deodorizing operation will be started. The control part 18 detects the room temperature T in the toilet room 100 based on the output of the temperature detection part 17 in step S22.

  Next, the control unit 18 selects and executes any one of steps S23 to S25 from the room temperature T in the toilet room 100 detected in step S22. In steps S23 to S25, the amount of water supplied from the spray unit 50 to the deodorizing filter 48 is set in step S26 described later.

  Specifically, when the room temperature T is 30 degrees or more, the control unit 18 executes step S23 and sets the supply water amount to 14 mL. Moreover, when the room temperature T is 10 degree | times or more and less than 30 degree | times, the control part 18 performs step S24, and sets supply water volume to 10 mL. Moreover, when room temperature is less than 10 degree | times, the control part 18 performs step S25, and sets supply water volume to 6 mL. That is, in the control part 18 of 2nd Embodiment, step S23-S25 is the water supply amount setting means 90 which sets the supply water quantity supplied to the deodorizing filter 48 based on the detection of the temperature detection part 17. FIG. In step S23, the amount of water set according to the room temperature T is smaller than the maximum water retention amount (about 20 mL) of the deodorizing filter 48.

  After the supply water amount is set by the water supply amount setting means 90, the control unit 18 executes step S26, and supplies functional water of the supply water amount set by the water supply amount setting means 90 from the spray unit 50 to the deodorizing filter 48. To do. For this reason, step S26 is water supply means 92 that instructs the spray unit 50 to supply the supply water amount set by the water supply amount setting means 90 to the deodorization filter 48.

  The amount of functional water supplied from the spray unit 50 varies depending on the room temperature T detected by the temperature detection unit 17. That is, since the amount of functional water supplied from the spray unit 50 changes, the amount of functional water held by the deodorizing filter 48 also changes. Here, when 14 mL of functional water, which is the supply water amount set in step S23, is supplied to the deodorization filter 48, the deodorization filter 48 is also in a state of holding about 14 mL of functional water, When 10 mL and 6 mL of functional water set in S25 are supplied, the amount of functional water held in the deodorizing filter 48 also changes in accordance with the change in the amount of supplied water. For example, when 10 mL of functional water is supplied, the water retention amount of the deodorization filter 48 is about 10 mL, and when 6 mL of functional water is supplied, the water retention amount of the deodorization filter 48 is also about 6 mL.

  Subsequently, after supplying functional water to the deodorizing filter 48 in step S26, the control unit 18 executes the deodorizing means 94 shown in steps S27 to S30. Specifically, first, in step S <b> 27, the execution of the water supply unit 92 is prohibited so that the functional water is not supplied from the spray unit 50. Thereby, functional water is not newly supplied to the deodorization filter 48 until the prohibition of the water supply means 92 is canceled in step S30 described later after the water supply means is executed in step S26. I have to.

  And the control part 18 performs step S28, and operates the fan 46. FIG. Thereby, since the air sucked from the air inlet 21 by the fan 46 passes through the deodorizing filter 48 in a state where the functional water is retained, the malodorous component contained in the air is collected or decomposed by the deodorizing filter 48.

  In step S28, the control unit 18 starts a timer (not shown). In subsequent step S29, the control unit 18 confirms whether or not a predetermined drying time has elapsed from the value of the timer. In the second embodiment, the predetermined drying time is 67.5 minutes. Therefore, the controller 18 repeats step S29 if the drying time of 67.5 minutes has not elapsed, and proceeds to step S30 if it has elapsed. In step S30, the prohibition of the water supply means 92 is canceled. Therefore, functional water can be supplied from the spray unit 50. At the same time, the fan 46 is stopped.

Since the execution of the water supply means 82 is prohibited until the prohibition of the functional water supply is canceled in step S30 after the functional water supply from the spray unit 50 is stopped in step S27, the deodorizing filter 48 is newly provided. Is not supplied with functional water.
Therefore, until the predetermined drying time elapses, the air sucked by the fan 46 is deodorized by the deodorizing filter 48 holding the functional water supplied by the water supply means 92 in step S26, and the drying time is set. When step S30 is executed after the elapse of time, the functional water supplied in step S26 is evaporated and the deodorizing filter 48 is in a dry state.

  As described above, in steps S27 to S30, after the functional water of the supply water amount is supplied to the deodorization filter 48 by the water supply means 92 in step S26, the fan 46 is operated to deodorize the air, and the predetermined drying is performed. Until time elapses, the water supply means 92 prohibits the supply of water and serves as a deodorizing means 94 for drying the deodorizing filter 48.

  When executing step S30, the control unit 18 ends the series of processes for deodorizing control in step S31. If the control unit 18 continues to operate, the process returns to step S20, and the processes of steps S20 to S31 are repeated again.

<Explanation of timing chart>
Next, timing charts shown in FIGS. 17 and 18 regarding the states of the fan 46, the spray unit 50, and the deodorizing filter 48 in the deodorizing operation executed by the control unit 18 of the second embodiment shown in FIG. It explains using.

  First, the case where the room temperature T is less than 10 degrees will be described with reference to FIG. In FIG. 17, the usage frequency information is not different from that in the first embodiment, and therefore the usage frequency information is not shown.

  As shown in FIG. 17, also in the control unit 18 of the second embodiment, when the current time is 1.5 units (67.5 minutes) before the “time zone to be used”, the process of step S21 shown in FIG. Since the condition is satisfied, the deodorizing operation after step S22 is executed. Therefore, the water supply amount setting means 90 and the water supply means 92 are executed at the timing t23 shown in FIG.

  In FIG. 17, since the room temperature T is less than 10 degrees, the water supply amount setting means 90 selects and executes step S25, and the supply water amount is set to 6 mL. Thereafter, the water supply unit 92 is executed at timing t23, and functional water is supplied from the spray unit 50 to the deodorizing filter 48 from timing t23 to t24. The timing t23 to t24 at which the functional water is supplied is, for example, about 2 seconds, whereby 6 mL of functional water, which is the supply water amount set by the water supply amount setting means 90, is supplied to the deodorization filter 48. The deodorizing filter 48 holds about 6 mL of functional water by the functional water supplied from the spray unit 50.

  When the supply of functional water is completed at timing t24, the control unit 18 executes the deodorizing means 94 from timing t24 to t25. Therefore, the execution of the water supply means 92 is prohibited after the timing t24. Further, since the fan 46 starts to operate and the air sucked from the intake port 21 passes through the deodorizing filter 48 in a state where the functional water is retained, the malodorous component contained in the air is collected or removed by the deodorizing filter 48. Disassembled.

While the deodorizing means 94 is being executed, the supply of functional water from the spray unit 50 is prohibited, so that no new functional water is supplied to the deodorizing filter 48. Therefore, the deodorizing filter 48 is gradually dried over time from the timing t24 and is in a dry state at the timing t25 when the drying time of 67.5 minutes has elapsed.
On the other hand, between the timings t24 and t25, although the deodorizing filter 48 is gradually dried, the functional water is retained, so that malodorous components contained in the air passing through the deodorizing filter 48 are collected or decomposed. can do. Step S30 is executed at timing t25 when the drying time of 67.5 minutes has elapsed, and the prohibition of the water supply means 92 is released. Further, the operation of the fan 46 is stopped. Thereafter, step 31 is executed, and a series of deodorizing operations shown in FIG.

  Since the control unit 18 of this specific example continues to operate after the timing t25, the control unit 18 repeats the execution of steps S20 to S31 shown in FIG. Therefore, step S21 is executed again at timing t25. Since the usage frequency at the timing t25 is “time zone to be used”, the condition of step S21 is satisfied, and the control unit 18 executes the deodorizing operation after step S22 of FIG. Thereby, the water supply amount setting means 90 and the water supply means 92 are executed at timing t25, and the deodorizing means 94 is executed at timing t26.

  In the control unit 18 of the second embodiment, the water supply amount setting means 90 sets the amount of water supplied to the deodorizing filter 48 based on the room temperature T detected by the temperature detection unit 17. That is, the water supply amount setting means 90 is capable of holding the functional water in the deodorizing filter 48 for a predetermined drying time (67.5 minutes) during which the deodorizing means 94 is executed, and the drying time. The amount of supplied water is set so that the deodorizing filter 48 is in a dry state after a lapse of time.

Therefore, when the water supply unit 92 is executed at timing t25, since the predetermined drying time at timings t24 to t25 has elapsed, the deodorizing filter 48 is in a dry state. Therefore, functional water is supplied in the same state as when functional water is supplied at timing t23.
That is, at timing t <b> 25, the amount of functional water supplied from the spray unit 50 and held in the deodorizing filter 48 becomes the amount of water corresponding to the amount of water supplied set by the water supply amount setting means 90. Therefore, as shown in FIG. 17, when room temperature T is less than 10 degrees at timing t25, since 6 mL of functional water is supplied again, deodorizing filter 48 has a function of about 6 mL that is the same as timing t24 at timing t26. Water can be retained. As a result, when a predetermined drying time has elapsed again from timing t26 to t27, the deodorizing filter 48 can be brought into a dry state.

  On the other hand, when functional water is newly supplied in a state where the deodorizing filter 48 holds functional water, the amount of functional water held by the deodorizing filter 48 after executing the water supply means 92 is The deodorizing filter 48 is the total amount of the functional water retained when the water supply unit 92 is executed and the functional water newly supplied by the water supply unit 92. In addition, when the total amount exceeds the maximum water retention amount of the deodorizing filter 48, the functional water exceeding the maximum water retention amount is drained from the drain port 52. That is, the amount of functional water drained from the drain port 52 may be larger than when the water supply unit 92 is executed in a state where the deodorizing filter 48 is dry.

As described above, in the deodorizing operation performed by the control unit 18 of the second embodiment, the amount of water supplied to the deodorizing filter 48 in a dry state during the drying time predetermined by the water supply amount setting means 90 is supplied. Set as. Further, when this amount of supplied water is supplied by the water supply means 92, the water supply means 92 is not executed until a predetermined drying time has elapsed.
Therefore, the water supply means 92 can supply functional water after the deodorizing filter 48 is in a dry state, and more water can be supplied than when functional water is supplied in a state where the deodorizing filter 48 is not dry. The functional water is retained in the deodorizing filter 48, and the functional water discharged without being retained in the deodorizing filter 48 can be reduced.

  In addition, since functional water can be supplied again to the deodorizing filter 48 after the drying time has elapsed, the functional water is supplied again if the deodorizing operation is still in progress, so that the deodorizing filter 48 maintains the functional water. The malodorous component contained in the air sucked by the fan 46 can be repaired or decomposed and deodorized.

  Next, the case where the room temperature T in the toilet room 100 is 10 degrees or more and less than 30 degrees will be described with reference to FIG.

  Also in FIG. 18A, the control unit 18 satisfies the condition of step S21 shown in FIG. 16 when the use frequency is 67.5 minutes before the “use time zone” (timing t28). The deodorizing operation | movement after S22 is performed.

  Therefore, the control part 18 performs the water supply amount setting means 90 after detecting the room temperature T in step S22. In the water supply amount setting means 90, step S24 is selected and executed according to the room temperature T (10 degrees or more and less than 30 degrees) detected in step S22. Therefore, the water supply amount setting means 90 sets the supply water amount to 10 mL.

  And the control part 18 performs the water supply means 92 in the timing t28 shown to Fig.18 (a), and functional water is supplied from the spray part 50 to the deodorizing filter 48 from the timing t28-t29. Timing t28 to t29 at which the functional water is supplied is, for example, about 3 seconds, and the time for supplying the functional water from the spray unit 50 is longer than when the room temperature T shown in FIG. 17 is less than 10 degrees. As a result, 10 mL of functional water, which is the supply water amount set by the water supply amount setting means 90, can be supplied to the deodorization filter 48. The deodorizing filter 48 holds about 10 mL of functional water by the functional water supplied from the spray unit 50.

  In the deodorizing apparatus 16 of the present embodiment, the amount of functional water supplied to the deodorizing filter 48 is changed by changing the spraying time of the spraying unit 50, but the form of the spraying unit 50 is not limited to this. Any supply water amount set by the water supply amount setting means 90 may be used. For example, the supply amount of functional water may be changed by changing the supply amount per unit time.

  When the supply of functional water by the water supply means 92 is completed, the deodorizing means 94 is executed from timing t29 to t30. Even when the room temperature T is 10 degrees or more and less than 30 degrees, the drying time executed in the deodorizing means 94 is 67.5 minutes which is a predetermined drying time.

  In the case where the room temperature T is 10 degrees or more and less than 30 degrees, the deodorizing filter 48 dries faster than in the case where the room temperature T is less than 10 degrees. In order to maintain the state in which the filter 48 holds the functional water, it is necessary to increase the amount of the functional water held in the deodorizing filter 48.

  In the control part 18 of 2nd Embodiment, since step S24 is selected and performed in the water supply amount setting means 90 according to this change of the room temperature T, the supply water amount is larger than the case where it is less than 10 degrees. Set to 10 mL. Therefore, as shown at timing t29 in FIG. 18A, when the room temperature T is 10 degrees or more and less than 30 degrees, the amount of functional water retained in the deodorizing filter 48 is larger than when the room temperature T is less than 10 degrees. About 10 mL.

  Similarly, when the room temperature T in the toilet room 100 is 30 degrees or more, the water supply amount setting means 90 selects and executes Step S23, so the supply water amount is set to 14 mL. Therefore, as shown at timing t34 in FIG. 18B, when the room temperature T is 30 degrees or more, the amount of functional water retained in the deodorizing filter 48 is 10 when the room temperature T shown in FIG. Compared to the case of more than 30 degrees and less than 30 degrees, it is about 14 mL more.

When the room temperature T is higher than when the room temperature T is low, the amount of functional water evaporated per unit time from the deodorizing filter 48 increases. That is, for the same drying time, the amount of functional water evaporated from the deodorizing filter 48 increases when the room temperature T is higher than when the room temperature T is low.
Therefore, the water supply amount setting means 90 can set the supply water amount in accordance with the deodorizing filter 48 in which the amount of evaporation varies according to the room temperature T by setting the supply water amount as the room temperature T becomes higher.

  Accordingly, when the room temperature T is high, the amount of supplied water is set to be small, so that the functional water is not retained in the deodorizing filter 48 despite the deodorizing operation being performed, and the room temperature T is low. In this case, it is possible to prevent the functional water from being supplied in a state where the supply water amount is set to be large and the deodorizing filter 48 is not dried. Therefore, the functional water can be supplied after the deodorizing filter 48 is dried, and the functional water discharged without being held by the deodorizing filter 48 can be reduced. Further, during the deodorizing operation, the deodorizing filter 48 can be maintained in a state of holding the functional water, and the deodorizing effect of air by the deodorizing filter 48 can be obtained.

<Effects of Second Embodiment>
As described above, in the control unit 18 of the second embodiment, the water supply amount setting unit 90 sets the supply amount of functional water supplied by the water supply unit 92 based on the detection of the temperature detection unit 17. Since the execution of the water supply means 92 is prohibited until the drying time predetermined by the deodorizing means 94 elapses, once the water supply means 92 is executed, the next water supply means until the drying time elapses. 92 is not executed. While the execution of the water supply means 92 is prohibited by the deodorizing means 94, the air sucked by the fan 46 passes through the deodorizing filter 48, so that malodorous components contained in the air outside the toilet seat device 1 are deodorized. . Further, the deodorized filter 48 is gradually dried as the sucked air passes, and the functional water supplied by the water supply means 92 is dried when the drying time elapses. That is, the water supply amount setting means 90 sets the amount of water in which the deodorizing filter 48 is dried during a predetermined drying time as the supply water amount.

Therefore, the water supply means 92 can supply functional water after the deodorizing filter 48 is in a dry state, and more water can be supplied than when functional water is supplied in a state where the deodorizing filter 48 is not dry. The functional water is retained in the deodorizing filter 48, and the functional water discharged without being retained in the deodorizing filter 48 can be reduced.
In addition, since functional water can be supplied again to the deodorizing filter 48 after the drying time has elapsed, when deodorizing by the deodorizing filter 48 is continued, the functional water is supplied again so that the deodorizing filter 48 holds the functional water. The odor contained in the air sucked from the fan 46 can be deodorized.

  Further, the amount of water evaporated from the deodorizing filter 48 per unit time increases as the room temperature T is higher than when the room temperature T is low. That is, for the same drying time, the amount of water evaporated from the deodorizing filter 48 increases when the room temperature T is higher than when the room temperature T is low. Therefore, the water supply amount setting means 90 can set the supply water amount in accordance with the deodorizing filter 48 in which the amount of water evaporated in accordance with the room temperature T changes by setting the supply water amount as the room temperature T becomes higher.

  As a result, when the room temperature T is high, the amount of supplied water is set to be small, so that the functional water is not held in the deodorizing filter 48 despite the middle of the drying time, and the room temperature T When the amount of water supplied is low, the amount of supplied water is set to be large, and the supply of functional water in a state where the deodorizing filter 48 is not dried can be suppressed. Therefore, according to such a configuration, the functional water can be supplied after the deodorizing filter 48 is dried, and the functional water discharged without being held by the filter can be reduced. Further, the deodorizing filter 48 can be kept in a state of holding functional water until a predetermined drying time elapses.

<Third Embodiment>
Then, the control part 18 in 3rd Embodiment of this invention is demonstrated using FIG. FIG. 19 is a flowchart illustrating a specific example of the deodorizing operation in the control unit 18 according to the third embodiment. Since FIG. 19 is a flowchart for explaining the deodorizing operation executed by the control unit 18, the process for storing presence / absence of human body detection by the human body detection sensor 13, the process for setting the use frequency, and the use by the cleaning nozzle 15 The local cleaning process of the person is omitted.

  When the toilet seat apparatus 1 and the control unit 18 are powered on, the control unit 18 repeatedly executes the processes of steps S40 to S50 in FIG. 19 until the power is turned off. As shown in FIG. 19, the control unit 18 starts operation from step S40. First, in step S41, the control unit 18 determines whether the current time is, for example, 67.5 minutes before the “use time zone” or the “use time zone”. If the current time is either 67.5 minutes before the “use time zone” or the “use time zone”, the process proceeds to step S42; otherwise, step S41 is repeated. .

  That is, the control unit 18 performs the deodorizing operation to execute the water supply unit 82, the drying time setting unit 80, and the deodorizing unit 84, which will be described later, from 67.5 minutes before 1.5 hours before the “use time zone”. The deodorizing operation is continued until the “use time period” elapses. The deodorizing operation is stopped in other time zones.

  In this way, by performing the deodorizing operation from 67.5 minutes before the usage frequency becomes the “use time zone”, before the time zone when the user is more likely to enter the toilet room 100, It is possible to remove the odor that is always present in the toilet room 100. Therefore, it is possible to prevent the user from feeling uncomfortable by sucking the odor that is always present in the toilet room 100.

  In this specific example, it has been described that the control unit 18 performs the deodorizing operation 67.5 minutes before the usage frequency becomes the “usage time zone”, but the time for starting the deodorizing operation is limited to this. As long as it is possible to remove the odor that is always present in the toilet room 100 before the time period when the usage frequency is high, the time for starting the deodorizing operation can be changed as appropriate.

  When the deodorizing operation is started in step S1, the control unit 18 proceeds to step S42. In step S42, the control unit 18 detects the room temperature T, which is the temperature of the air in the toilet room 100, as the environmental temperature based on the output of the temperature detection unit 17.

  Next, since the control unit 18 executes the drying time setting means 100, the control unit 18 selects and executes one of steps S43 to S45 from the room temperature T detected in step S42. To do. In steps S43 to S45, the drying time required until the deodorizing filter 48 supplied with the functional water in a predetermined supply water amount is dried in step S46 described later is set.

  After the drying time is set in the drying time setting unit 100, the control unit 18 executes the water supply unit 102 in step S46, and supplies functional water from the spray unit 50 to the deodorizing filter 48. At this time, the spray unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorizing filter 48 for, for example, about 3 seconds to 5 seconds. Thereby, the deodorizing filter 48 will be in the state holding the functional water of the maximum water retention amount (about 20 mL). The amount of functional water supplied from the spray unit 50 to the deodorizing filter 48 in the water supply unit 82 is constant and does not change according to the room temperature T detected by the temperature detection unit 17.

  Moreover, in the control part 18 of this specific example shown in FIG. 12, the water supply means 102 shown in step S6 is executed after the drying time setting means 100 shown in steps S43 to S45. Operation | movement of the control part 18 is not limited to this, For example, you may perform the water supply means 102 before detecting the room temperature T of step S2, and the step S43-S45 which is the drying time setting means 100 may be performed. You may go before.

  The operation of the control unit 18 in the drying time setting unit 100 and the water supply unit 102 in the third embodiment is the same as that of the drying time setting unit 80 and the water supply unit 92 in the first embodiment.

  Subsequently, after supplying the functional water to the deodorizing filter 48 in step S46, the control unit 18 executes the deodorizing means 84 shown in steps S47 to S49. Specifically, first, the control unit 18 executes step S47 to operate the fan 46. Thereby, since the air sucked from the air inlet 21 by the fan 46 passes through the deodorizing filter 48 in a state where the functional water is retained, the malodorous component contained in the air is collected or decomposed by the deodorizing filter 48.

  In step S47, the control unit 18 starts a timer (not shown). In subsequent step S48, the control unit 18 confirms whether or not the drying time set in steps S43 to S45 has elapsed from the value of the timer. The controller 18 repeats step S48 if the drying time has not elapsed, and proceeds to step S49 if the drying time has elapsed. In step S49, the fan 46 is stopped.

  Then, after the drying time has elapsed in step S49 and the fan 46 has been stopped, the control unit 18 ends a series of processes of deodorization control in step S50, but when the deodorization filter 48 continues to deodorize air, Returning to step S40, the processes of steps S40 to S50 are repeated again. Then, the functional water is supplied again to the deodorizing filter 48 in the water supply means 102 in step S46.

  That is, in the control unit 18 according to the third embodiment, after functional water is supplied from the spray unit 50 in step S46, the fan 46 is operated to deodorize the air, and the drying set by the drying time setting unit 100 is performed. If time passes, it will return to step S0 and will perform steps S40-S46 again, and functional water will be supplied to the deodorizing filter 48. FIG.

<Effect of the third embodiment>
As described above, in the control unit 18 according to the third embodiment, the drying time setting unit 100 determines the time until the functional water supplied by the water supply unit 102 is dried based on the detection of the temperature detection unit 17. Set. Then, after the supply amount of functional water is supplied to the deodorizing filter 48, the fan 46 is operated until the drying time elapses, and air is passed through the deodorizing filter 48 holding the functional water to perform deodorization. The functional water supplied to is dried. Then, since the deodorizing filter 48 is in a dry state after the drying time has elapsed, when the deodorizing filter 48 continues to deodorize air, functional water is supplied to the deodorizing filter 48 again. That is, in the drying time setting means 100, the time required for the deodorizing filter 48 supplied with the predetermined amount of functional water to be dried is set as the drying time.

  Therefore, the water supply means 102 can supply functional water to the deodorizing filter 48 after the drying time has elapsed and the deodorizing filter 48 is in a dry state. Accordingly, more functional water is retained in the deodorizing filter 48 and less functional water is discharged without being retained by the deodorizing filter 48 than when functional water is supplied in a state where the deodorizing filter 48 is not dried. can do.

  In the third embodiment, since the supply of the functional water to the deodorizing filter 48 is not prohibited until the drying time elapses after the functional water is supplied from the spray unit 50, an exceptional process occurs. When it is necessary to supply functional water to the deodorizing filter 48, the functional water may be supplied to the deodorizing filter 48 even before the drying time has elapsed.

<Fourth embodiment>
Then, the control part 18 in 4th Embodiment of this invention is demonstrated using FIG. FIG. 20 is a flowchart illustrating a specific example of the deodorizing operation in the control unit 18 according to the fourth embodiment. FIG. 20 is a flowchart for explaining the deodorizing operation executed by the control unit 18, so that the storage process of presence / absence of human body detection by the human body detection sensor 13, the use frequency setting process, and the use by the cleaning nozzle 15 are used. The local cleaning process of the person is omitted.

  As shown in FIG. 20, the control unit 18 starts operation from step S60. As in the first embodiment, in step S61, the control unit 18 determines whether the current time is 67.5 minutes before the “use time zone” or the “use time zone”. If the current time is either 67.5 minutes before the “use time zone” or the “use time zone”, the process proceeds to step S62; otherwise, step S61 is repeated. .

  And if the conditions of step S61 are satisfy | filled, it will progress to step S62 and deodorizing operation will be started. The control part 18 detects the room temperature T in the toilet room 100 based on the output of the temperature detection part 17 in step S62.

  Next, in order to execute the water supply amount setting means 110, the control unit 18 selects and executes any one of steps S63 to S65 from the room temperature T in the toilet room 100 detected in step S62. In steps S23 to S25, the amount of water supplied from the spray unit 50 to the deodorizing filter 48 is set in step S26 described later.

  Then, after the water supply amount is set in the water supply amount setting means 110, the control unit 18 executes the water supply means 112 in step S66, and the function of the supply water amount set by the water supply amount setting means 90 from the spray unit 50. Water is supplied to the deodorizing filter 48. In the fourth embodiment, the water supply amount setting means 110 and the water supply means 112 executed by the control unit 18 operate in the same manner as the water supply amount setting means 90 and the water supply means 91 of the second embodiment. .

  Subsequently, after supplying the functional water to the deodorizing filter 48 in step S66, the control unit 18 executes the deodorizing unit 114 shown in steps S67 to S69. Specifically, first, step S67 is executed to operate the fan 46. Thereby, since the air sucked from the air inlet 21 by the fan 46 passes through the deodorizing filter 48 in a state where the functional water is retained, the malodorous component contained in the air is collected or decomposed by the deodorizing filter 48.

  In step S67, the control unit 18 starts a timer (not shown). In subsequent step S68, the control unit 18 confirms whether or not a predetermined drying time has elapsed from the value of this timer. In the fourth embodiment, the predetermined drying time is 67.5 minutes. Therefore, the control unit 18 repeats Step S68 if the drying time of 67.5 minutes has not elapsed, and proceeds to Step S69 if it has elapsed. In step S69, the fan 46 is stopped.

  Then, after the drying time has elapsed and the fan 46 has been stopped in step S69, the control unit 18 ends the series of processes of deodorization control in step S70, but when the deodorization filter 48 continues to deodorize air, Returning to step S60, the processes of steps S60 to S70 are repeated again. Then, the functional water is supplied again to the deodorizing filter 48 in the water supply means 112 in step S66.

  That is, in the control unit 18 according to the fourth embodiment, after the functional water having the supply water amount set by the water supply amount setting unit 110 is supplied from the spray unit 50 in step S66, the fan 46 is operated to deodorize the air. When a predetermined drying time has elapsed, the process returns to step S60 and steps S60 to S66 are executed again to supply functional water to the deodorizing filter 48.

<Effects of Fourth Embodiment>
As described above, in the control unit 18 according to the fourth embodiment, the water supply amount setting unit 110 sets the supply amount of functional water supplied by the water supply unit 112 based on the detection of the temperature detection unit 17. . The fan 46 is operated until a predetermined drying time elapses after the supply amount of functional water is supplied to the deodorizing filter 48, and air is passed through the deodorizing filter 48 holding the functional water to perform deodorization. The functional water supplied to the deodorizing filter 48 is dried. When the predetermined drying time elapses, the deodorizing filter 48 is in a dry state. Therefore, when the deodorizing filter 48 continues to deodorize air, functional water is supplied to the deodorizing filter 48 again. That is, the water supply amount setting means 110 sets the amount of water in which the deodorizing filter 48 is dried during a predetermined drying time as the supply water amount.

  Therefore, the water supply means 112 can supply the functional water after the deodorizing filter 48 is in a dry state, and more water can be supplied than when the functional water is supplied in a state where the deodorizing filter 48 is not dry. The functional water is retained in the deodorizing filter 48, and the functional water discharged without being retained in the deodorizing filter 48 can be reduced.

  In the fourth embodiment, since the supply of the functional water to the deodorizing filter 48 is not prohibited until the drying time elapses after the functional water is supplied from the spray unit 50, an exceptional process occurs. When it is necessary to supply functional water to the deodorizing filter 48, the functional water may be supplied to the deodorizing filter 48 even before the drying time has elapsed.

<Modification>
As mentioned above, although embodiment of the technique which this application discloses was described, the technique which this application discloses is not limited above.

  For example, the spray unit 50 supplies functional water to the deodorization filter 48, but the deodorization device 16 of the toilet seat device 1 of the present invention is not limited to this. For example, water or hot water is supplied from the spray unit 50 to the deodorization filter 48. May be provided.

  Moreover, although the spray part 50 supplied by spraying functional water on the deodorizing filter 48, the spray part 50 of this invention is not limited to this, and makes the deodorizing filter 48 hold | maintain functional water. If possible, the form can be changed as appropriate.

  In FIG. 16, the supply water amount set in steps S23, S24, and S25 has been described as being set to a value smaller than the maximum water retention amount (about 20 mL) of the deodorization filter 48. The relationship between the maximum water retention amount and the supply water amount of the deodorizing filter 48 is not limited to this, and a supply water amount larger than the maximum water retention amount may be set. Moreover, each supply water amount and the maximum water retention amount of the deodorizing filter 48 can be changed suitably.

  Moreover, in the toilet seat apparatus 1 of this specific example, the drying time setting means 80 is based on the room temperature T detected by the temperature detection part 17, as demonstrated by step S2 of FIG. 12, and step S22 of FIG. The drying time and the water supply amount setting means 90 set the supply water amount. On the other hand, the drying time setting means 80 and the water supply amount setting means 90 are based on a humidity detection unit capable of detecting the humidity of air, instead of the room temperature T detected by the temperature detection unit 17, or It is also preferable that the amount of water supply can be set.

  In such a case, a humidity detection unit (not shown) is disposed between the deodorization filter 48 and the exhaust port 54, and whether the deodorization filter 48 is dry by detecting the humidity of the air after passing through the deodorization filter 48. Can be judged.

  The elements included in each of the embodiments described above can be combined as much as technically possible, and combinations thereof are also included in the scope of the present invention as long as they include the features of the present invention.
