Description

  Aspects of the invention generally relate to a sanitary washing apparatus.

  For example, there is a deodorizing and sterilizing device for a flush toilet provided with an intake device and a sterilizing water supply device (Patent Document 1). The deodorizing and sterilizing apparatus for flush toilets described in Patent Document 1 supplies electrolytic water, that is, sterilized water to a moisturizing filter and impregnates it in order to remove malodorous components generated in the 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 filter, the malodorous component is absorbed or decomposed by the impregnated electrolyzed water.

  When a filter containing electrolyzed water absorbs or decomposes malodorous components, substances that cause odors are adsorbed on the filter. Therefore, the filter deodorizing performance may not be ensured unless the filter is maintained. The deodorizing and sterilizing apparatus described in Patent Document 1 supplies new sterilizing water to the filter after deodorizing, and removes malodorous components, dust, germs, and the like attached at the same time as cleaning. Therefore, there is room for improvement with respect to the life and water saving of the sterilizing water supply device. Efficient cleaning is desired for filters that absorb or decompose malodorous components.

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 sanitary washing device according to an embodiment of the present invention is installed.
FIG. 2 is a schematic perspective view showing the sanitary washing 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 sanitary washing device 1. The sanitary washing 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 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.

  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 user-friendly sanitary washing device 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 illustrated in FIG. 2, the intake port portion 21 and the exhaust port portion 22 are provided on the same surface (left surface) of the case cover 10. Therefore, compared with the case where the intake port portion 21 and the exhaust port portion 22 are provided on different surfaces, the intake port portion 21 easily sucks the air exhausted from the exhaust port portion 22 again. Therefore, the air inlet 21 can suck again the air containing the malodorous component that has not been collected or decomposed by the deodorizing device 16. Thereby, the malodorous component contained in the partially stagnant odor can be intensively collected or decomposed.

  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, 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.

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 bath 28, an air release type vacuum breaker (VB) 30, a washing The first flow path 32 communicated with the nozzle 14, the second flow path 34 communicated with the deodorizing device 16, the electromagnetic pump 36, and the 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 the formula (1) occurs at the anode (for example, the first electrode 28a).

Cl ⁻ → e ⁻ + 1 / 2Cl ₂ (1)

Chlorine generated in formula (1) is unlikely to exist as bubbles, and most of the chlorine dissolves in water. Therefore, for the chlorine generated in formula (1), the reaction represented by formula (2) occurs.

Cl ₂ + H ₂ O → HClO + H ⁺ + Cl ⁻ (2)

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 upward from the water discharge unit 15. The functional water discharged from the water discharge unit 15 is used for local cleaning of the user of the toilet 2.

  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.

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 deodorizing device 16 includes a dust collection filter 44, a fan (air blowing unit) 46, a deodorizing filter 48, a spraying unit 50, a water receiving unit 52, and a filter case 72. ,have.

  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 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 removed from the sanitary washing 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, in the present specification, the “porous structure” refers to a structure that is a cube having a weight of 1 g and a cube having a side length of 1 cm and 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.

  The functional water is sprayed on 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 on which the functional water is sprayed. 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 sanitary washing device 1 before the fan 46 operates always passes through the deodorizing filter 48 and is discharged to the toilet room 100 after malodorous components are collected. Therefore, when the fan 46 is operated, the air accumulated inside the sanitary washing device 1 can be prevented from being discharged to 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 the material of the deodorizing filter 48 without forming a water film in the honeycomb structure 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.

HClO + NH ₃ → NH ₂ Cl + H ₂ O (3)

As shown in Formula (3), ammonia (NH ₃ ) reacts with hypochlorous acid (HClO) to change into monochloramine (NH ₂ Cl) and water (H ₂ O). 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 sanitary washing device 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. 7 is a schematic perspective view illustrating a specific example of a deodorizing filter and a filter case. 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 deodorizing filter when viewed in the direction of the arrow A31 illustrated in FIG. That is, FIG. 8A and FIG. 8B are schematic plan views illustrating specific examples of the deodorizing filter and the filter case as viewed from above.
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. 8A and FIG. 8B, the length in the first direction (the horizontal direction in FIG. 8A) of the portion of the filter case 72 that holds the deodorizing filter 48 is shown. The length D1 is longer than the length D3 of the deodorizing filter 48 in the first direction. The length D2 in the second direction (vertical direction in FIG. 8A) of the portion of the filter case 72 that holds the deodorizing filter 48 is longer than the length D4 of the deodorizing filter 48 in the second direction. Also long. That is, there is a gap between the deodorizing filter 48 and the filter case 72 in a state where the deodorizing filter 48 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 deodorizing filter 48 has a honeycomb structure. In the specific examples shown in FIGS. 8B and 9A, the deodorizing filter 48 has a structure in which the holes 48a of the square pillars are arranged. As in the specific example shown in FIG. 9B, the deodorizing filter 48 of the present embodiment may have a structure in which triangular prism holes 48b are arranged. Or the deodorizing filter 48 of this embodiment may have the structure where the hole 48c of the hexagonal column was located in a line like the specific example represented to FIG.9 (c).

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 structure of the deodorizing filter 48 has when viewed from the upper side to the lower side.

  The axis of the solid figure of the honeycomb structure of the deodorizing filter 48 is parallel to the vertical direction. The three-dimensional figure axis of the honeycomb structure of the deodorizing filter 48 refers to the axis of a square pillar hole in the specific example shown in FIG. In the specific example shown in FIG. 9B, the axis of the three-dimensional figure that the honeycomb structure of the deodorizing filter 48 has means the axis of a triangular prism hole. The three-dimensional figure axis of the honeycomb structure of the deodorizing filter 48 is the axis of a hexagonal column hole in the specific example shown in FIG.

  According to this, water is sufficiently distributed in the vertical direction of the deodorizing filter 48. Therefore, substantially the entire deodorizing filter 48 is in a state of holding water. Thereby, the sanitary washing apparatus 1 concerning this embodiment can ensure higher deodorizing performance.

FIG. 10 is a schematic plan view showing the inside of the sanitary washing 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 10 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, it is possible to prevent the user from recognizing that the sanitary cleaning device 1 is out of order.

Next, a specific example of the operation of the sanitary washing device 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 adjacent to each other (90 minutes). 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.

FIG. 12 is a timing chart illustrating a specific example of the operation of the sanitary washing device according to this embodiment.
This specific example is an example of a normal cleaning operation of the deodorizing filter 48. In this specific example, eight days or more have passed since the user used the toilet room 100. The control unit 18 of this specific example controls the cleaning operation of the deodorizing filter 48 in the first “non-use time period” within one day (24 hours). That is, the control unit 18 of this specific example controls the cleaning operation of the deodorizing filter 48 at a frequency of at least once per day.

  When the usage frequency reaches the “use time zone”, the control unit 18 starts the operation of the fan 46 and executes control to spray the functional water from the spray unit 50 (timing t1). The spray unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorizing filter 48 for about 3 seconds to 5 seconds, for example. The deodorizing filter 48 holds the maximum amount of functional water.

  Since the fan 46 is operating in a state where the deodorizing filter 48 holds the functional water, malodorous components contained in the air sucked from the air inlet 21 are collected or decomposed by the deodorizing device 16. That is, the deodorizing operation by the deodorizing device 16 is performed. The deodorizing operation by the deodorizing device 16 is performed until the deodorizing filter 48 is dried.

  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 prior to absorbing or retaining water. To do. The time from when the deodorizing filter 48 of the present embodiment holds the maximum water holding amount of water until it is dried by the air sent from the fan 46 is, for example, about 30 minutes to 2 hours.

  Since the deodorizing operation is performed until the deodorizing filter 48 is dried, the deodorizing filter 48 is dry when the deodorizing operation is not performed. Thereby, it is possible to suppress the propagation of bacteria such as cocoons in the deodorizing filter 48.

  When the deodorizing filter 48 is dried, the control unit 18 performs control to spray the functional water from the spray unit 50 (timing t2). The spray unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorizing filter 48 for about 3 seconds to 5 seconds, for example. Thereby, the deodorizing filter 48 holds the maximum amount of functional water.

Subsequently, when the usage frequency becomes “a time slot that is not frequently used”, the control unit 18 executes control to stop the operation of the fan 46 (timing t3).
Subsequently, when the usage frequency becomes a “non-use time zone”, the control unit 18 controls the cleaning operation of the deodorizing filter 48 (timing t4). That is, in this specific example, the “non-use time zone” described above with reference to FIG. 10 corresponds to the “non-use time zone”.

  More specifically, the control part 18 performs control which sprays functional water from the spray part 50 in the state which stopped operation | movement of the fan 46 (timing t4). The spray unit 50 sprays about 24 mL or more and 26 mL or less of functional water toward the deodorizing filter 48 for about 5 seconds to 7 seconds, for example. Subsequently, when about 1 minute has elapsed since the spraying of the functional water, the spraying unit 50 supplies about 24 mL or more and 26 mL or less of functional water to the deodorizing filter 48 for about 5 seconds or more and 7 seconds or less, for example. Spray again towards. The spray unit 50 repeats such an operation, and sprays functional water onto the deodorizing filter 48 a plurality of times during a predetermined time (timing t4 to t5). In this specific example, in the cleaning operation of the deodorization filter 48, the spray unit 50 sprays the functional water on the deodorization filter 48 six times, and supplies about 150 mL of functional water to the deodorization filter 48 in total, for example.

  Subsequently, the control unit 18 starts the operation of the fan 46 45 minutes before the use frequency is switched to the “use time zone”, and executes control to spray the functional water from the spray unit 50 (timing t6). When the deodorizing filter 48 is dried, the control unit 18 performs control to spray functional water from the spray unit 50 (timing t7). At timing t <b> 6 and timing t <b> 7, the spray unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorizing filter 48 for about 3 seconds to 5 seconds, for example. Thereby, the deodorizing filter 48 holds the maximum amount of functional water.

  According to this, 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.

  According to this specific example, the deodorizing filter 48 for deodorizing the inside of the toilet room 100 can be washed during a non-use time period. Thereby, the deodorizing filter 48 can be more efficiently cleaned, and the deodorizing filter 48 can be made maintenance-free for a long period of time. In addition, by performing the cleaning operation of the deodorizing filter 48 during a non-use time period, it is possible to suppress the possibility that the user will know how to clean the deodorizing filter 48.

Moreover, since the cleaning operation of the deodorizing filter 48 is executed at least once a day, the deodorizing performance of the deodorizing filter 48 can be ensured.
In addition, since the operation of the fan 46 is stopped during the cleaning operation of the deodorizing filter 48, the spray unit 50 can spray functional water at an arbitrary position. For example, the functional water sprayed from the spray unit 50 can be prevented from coming out of the deodorizing device 16 or the sanitary washing device 1.

Moreover, the control part 18 may reverse the polarity of the voltage applied between the electrodes of the electrolytic cell 28 for every spray of functional water, when performing the control which sprays functional water from the spray part 50 in multiple times. (Timing t4 to t5). For example, the control unit 18 sets the first electrode 28a as an anode and sets the second electrode 28b as a cathode to generate and spray functional water. The first electrode 28a is set as the cathode, and the second electrode 28b is set as the anode. By performing polarity reversal (pole change) in the cleaning operation of the deodorizing filter 48, generation of scales such as calcium carbonate (CaCO ₃ ) can be suppressed. Thereby, it can suppress that the electrolysis efficiency of the electrolytic vessel 28 falls and the production | generation efficiency of sterilization water falls. Further, the spraying unit 50 sprays the functional water a plurality of times, so that the time during which the flow path opening / closing valve 24 is open can be suppressed and the heat generated in the circuit board or the like can be suppressed.

  In this specific example, when there is no “unused time zone” of the usage frequency, the cleaning operation of the deodorizing filter 48 is the first of the 32 units divided into 45 minutes every day. It may be executed when it becomes a unit. Alternatively, in this specific example, when there is no “usage time zone” of the usage frequency, the cleaning operation of the deodorizing filter 48 is the first “usage time zone” in the first day of usage frequency. It may be executed when. That is, in the specific example shown in FIG. 12, when there is no “usage time period” of the usage frequency, the cleaning operation of the deodorizing filter 48 may be started at the timing t3.

  Further, the control of the cleaning operation of the deodorizing filter 48 may be executed according to a user instruction. More specifically, the user may control the cleaning operation of the deodorizing filter 48 by operating the operation unit 74 (see FIG. 1). According to this, the user can execute the cleaning operation of the deodorizing filter 48 at an arbitrary timing.

FIG. 13 is a timing chart illustrating another specific example of the operation of the sanitary washing device according to this embodiment.
This specific example is an example in which the cleaning operation of the deodorizing filter 48 is performed for the first time after the sanitary washing device 1 is installed.

  The control unit 18 does not control the cleaning operation of the deodorizing filter 48 on the first day after the sanitary washing device 1 is installed. The control unit 18 executes the control of the cleaning operation of the deodorizing filter 48 for the first time on the second day after the sanitary cleaning device 1 is installed. Therefore, this specific example is an example of the second day after installation of the sanitary washing device 1. On the second day after the installation of the sanitary washing apparatus 1, the control unit 18 is accumulating data (number of times of use) for setting the use frequency described above with reference to FIG. It cannot be executed.

  Therefore, in this specific example, on the second day after the installation of the sanitary washing device 1, when the first unit among the 32 units obtained by dividing one day every 45 minutes, the control unit 18 performs the deodorizing filter. 48 cleaning operation control is executed (timing t11). That is, in this specific example, the “non-use time zone” described above with reference to FIG. 10 corresponds to the time zone of the first unit among the 32 units obtained by dividing one day every 45 minutes. When the fan 46 is operating, the control unit 18 stops the operation of the fan 46 and controls the cleaning operation of the deodorizing filter 48.

  The spray time of functional water, the spray amount of functional water, and the number of sprays of functional water are as described above with respect to the timings t4 to t5 in the specific example illustrated in FIG. 12 (timing t11 to t12).

  Subsequently, when the cleaning operation of the deodorizing filter 48 is completed, the control unit 18 executes control to start the operation of the fan 46 (timing t12). Since the fan 46 is operating in a state where the deodorizing filter 48 holds the functional water, malodorous components contained in the air sucked from the air inlet 21 are collected or decomposed by the deodorizing device 16. That is, the deodorizing operation by the deodorizing device 16 is performed. The deodorizing operation by the deodorizing device 16 is performed until the deodorizing filter 48 is dried (timing t13).

  Subsequently, the control unit 18 performs control to stop the operation of the fan 46 after the deodorizing filter 48 is dried (timing t14).

FIG. 14 is a timing chart illustrating still another specific example of the operation of the sanitary washing device according to this embodiment.
This specific example is an example of the fifth day after the installation of the sanitary washing device 1. The control unit 18 is accumulating data (number of uses) for setting the use frequency described above with reference to FIG. Therefore, the control unit 18 of this specific example sets the use frequency based on data (number of times of use) accumulated from the first day to the fourth day after the installation of the sanitary washing device 1.

  When it becomes the first unit among the 32 units obtained by dividing one day every 45 minutes, the control unit 18 executes control to start the operation of the fan 46 (timing t21). Then, the control part 18 performs control which sprays functional water from the spraying part 50 67.5 minutes before a use frequency switches to "the time zone to be used" (timing t22). When the deodorizing filter 48 is dried, the control unit 18 performs control to spray functional water from the spray unit 50 (timing t23). At timing t <b> 22 and timing t <b> 23, the spray unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorizing filter 48 for about 3 seconds to 5 seconds, for example. Thereby, the deodorizing filter 48 holds the maximum amount of functional water.

  According to this, 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.

Subsequently, when the usage frequency becomes a “non-use time zone”, the control unit 18 controls the cleaning operation of the deodorizing filter 48 (timing t24 to t25). That is, in this specific example, the “non-use time zone” described above with reference to FIG. 10 corresponds to the “non-use time zone”. The operations at timings t24 to t25 are the same as the operations described above with respect to the timings t4 to t5 in the specific example shown in FIG.
Subsequently, the control unit 18 executes control to stop the operation of the fan 46 after the deodorizing filter 48 is dried (timing t26).

  According to this specific example, even if the control unit 18 is accumulating data for setting the usage frequency, the usage frequency is set based on the data accumulated up to the previous day. Therefore, the control unit 18 can control the cleaning operation of the deodorizing filter 48 based on the use frequency based on the data accumulated up to the previous day even when the data for setting the use frequency is being accumulated.

FIG. 15 is a flowchart illustrating yet another specific example of the operation of the sanitary washing device according to this embodiment.
In this specific example, the control unit 18 determines whether or not the accumulated time of the operation of the fan 46 has passed a predetermined time (step S11). When the accumulated time of the operation of the fan 46 has passed the predetermined time (step S11: Yes), the control unit 18 controls the cleaning operation of the deodorizing filter 48 (step S13). On the other hand, when the accumulated time of the operation of the fan 46 has not passed the predetermined time (step S11: No), the control unit 18 operates the fan 46 without controlling the cleaning operation of the deodorizing filter 48. Is continued (step S15). The cleaning operation of the deodorizing filter 48 is the same as the operation described above with respect to the timings t4 to t5 of the specific example shown in FIG.

  The control unit 18 may determine whether or not the cumulative number of operations of the fan 46 has exceeded a predetermined number (step S11). In this case, when the cumulative number of operations of the fan 46 reaches a predetermined number (step S11: Yes), the control unit 18 controls the cleaning operation of the deodorizing filter 48 (step S13). On the other hand, when the cumulative number of operations of the fan 46 has not reached the predetermined number (step S11: No), the control unit 18 performs the operation of the fan 46 without controlling the cleaning operation of the deodorizing filter 48. Continue (step S15). The cleaning operation of the deodorizing filter 48 is the same as the operation described above with respect to the timings t4 to t5 of the specific example shown in FIG.

  According to this specific example, the cleaning operation of the deodorizing filter 48 can be performed according to the air volume passing through the deodorizing filter 48. Therefore, the deodorizing performance of the deodorizing filter 48 can be ensured.
