Description

SANITARY WASHING APPARATUS

Embodiments of the present invention generally relate to a sanitary cleaner.

For example, there is a deodorizing and sterilizing apparatus for a flush toilet having an intake apparatus and a sterilizing water supply apparatus (Patent Document 1). In the deodorizing and sterilizing apparatus of the flush toilet according to Patent Document 1, electrolytic water, that is, sterilizing water is supplied to a moisturizing filter to impregnate the flush toilet or the urinal to remove odor components generated in the flush toilet or the urinal. When the intake apparatus is operated, the odor is sucked from the toilet through the odor passage. The odor component is sucked or decomposed by the electrolytic water impregnated when the odor is passed through the filter.

In the case where the filter including the electrolytic water sucks or decomposes the odor component, the deodorization performance of the filter is related to the performance (maintenance performance) of the filter holding the electrolytic water. The air in the toilet is in a state of being humid by the staying water. Therefore, when the filter including the electrolytic water sucks or decomposes the odor component in the toilet bowl, the filter is relatively hard to dry even when the suction device sucks in the odor.

However, the air outside the toilet may be drier than the air in the toilet. Therefore, when the filter including the electrolytic water sucks or decomposes odorous components other than the toilet bowl, the filter is liable to be relatively dry when the suction device sucks the odor. In order to ensure the deodorization performance of the filter, a higher maintenance performance of the filter is desired.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and a detailed description thereof will be omitted.

1 is a schematic perspective view showing a toilet room provided with a sanitary washing apparatus according to an embodiment of the present invention.

2 is a schematic perspective view showing the sanitary washing apparatus according to the present embodiment.

As shown in Fig. 1, a toilet flush toilet 2 is provided inside the toilet room 100. As shown in Fig. A sanitary washing apparatus (1) is installed in the toilet (2). The sanitary washing apparatus 1 according to the present embodiment includes a toilet seat (not shown), a toilet seat cover 4, and a functional unit 6. [ For example, the user can open or close the toilet cover 4 or operate various functions of the function unit 6 by operating the operation unit 74 provided on the wall surface of the toilet room 100.

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, (14), a deodorizing device (16), and a control part (18). The toilet seat (not shown) and the toilet lid 4 are pivotally supported on the case cover 10 so as to be openable and closable. The case plate 8 is provided behind the bowl portion 20 of the toilet 10 when viewed from the front (front) of the toilet 10. A cleaning water supply device 12, a cleaning nozzle 14, a deodorizing device 16, and a control device 18 are provided in the case plate 8. The case cover 10 is fixed to the case plate 8 so as to cover the washing water supply device 12, the cleaning nozzle 14, the deodorizing device 16, and the control part 18.

The human body detecting sensor 13 is, for example, a pyrotechnic sensor using an infrared signal, and detects an occupant entering the bathroom room 100. The human body detecting sensor 13 may be a microwave sensor such as a Doppler sensor. When a sensor using a Doppler effect of a microwave or a sensor or the like for detecting a detection object on the basis of the amplitude (intensity) of a microwave reflected by transmitting a microwave is used as the human body detection sensor 13, the human body detection sensor 13 It is possible to detect the presence of the user over the door of the toilet room 100. In other words, the human body detecting sensor 13 can detect the user before entering the toilet room 100.

The deodorizer 16 is installed on the rear left side of the case plate 8 when viewed from the front of the toilet 10. 2, the deodorizing device 16 sucks the air in the toilet room 100 from the inlet port 21 formed on the left side of the case cover 10 when viewed from the front of the flusher 2 . The air in the toilet room 100 mainly refers to air outside the bowl 2 (air other than the bowl 20). The odor component contained in the air sucked from the inlet port portion (21) is collected or disassembled by the deodorizing device (16).

In the present specification, the upper side is referred to as "upward" when seen from a user who sits on the toilet 2 in a normal use state, and the lower side is referred to as "downward" when viewed from a user sitting on the toilet 2 in a normal use state. Further, the front side is referred to as " forward " when viewed from a user who sits on the toilet seat 2 in a normal use state, and the rear side is referred to as " rear " when viewed from a user sitting on the toilet seat 2 in a normal use state. The front side of the toilet 2 facing the direction of the toilet 2 is referred to as the front side when viewed from the front user and the inside side viewed from the front of the toilet 2 toward the direction of the toilet 2, " The right side is viewed as "right side" when viewed from the front of the toilet 2 toward the direction of the toilet 2 and the left side is referred to as "left side" when viewed from the front of the toilet 2 toward the toilet 2 Room ".

The " odor component " in the present embodiment includes an ammonia component. This odor component arises from the adhered portion of the urine when the urine is attached to the floor or wall of the toilet room 100 or the like.

Air from which odor components have been collected or decomposed by the deodorizing device 16 as shown by an arrow A29 in Fig. 2 flows from the exhaust port 22 formed on the left side of the case cover 10 And discharged to the toilet room 100.

Since the exhaust port portion 22 is formed on the side surface of the case cover 10, the air is not discharged to the front of the case cover 10. [ Therefore, it is possible to prevent the air discharged from the exhaust port 22 from directly contacting the user. Accordingly, it is possible to provide the sanitary washing apparatus (1) which is easy to use. The configuration of the intake port portion 21 and the exhaust port portion 22 is not limited to the example shown in Fig. For example, the intake port portion 21 may be formed on the rear surface (back surface) of the case cover 10. [ Or at least one of the intake port portion 21 and the exhaust port portion 22 may be formed on the right side surface.

In the example shown in Fig. 2, the intake port portion 21 and the exhaust port portion 22 are formed on the same surface (left surface) of the case cover 10. Therefore, as compared with the case where the intake port portion 21 and the exhaust port portion 22 are formed on different surfaces, the intake port portion 21 is easier to suck the air discharged from the exhaust port portion 22 again. Therefore, the intake port portion 21 can suck the air including the odor component that has not been captured or decomposed by the deodorization device 16 again. Accordingly, the odor component contained in the partially stagnant odor can be collectively collected or disassembled.

Further, the exhaust port 22 is formed on the front side of the intake port 21. Therefore, the air outlet portion 22 can exhaust the air in which the odor component is trapped or disassembled from the front side of the air inlet portion 21. Therefore, the user is liable to relatively inhale the air in which the odor component is trapped or decomposed. Therefore, it is possible to further inhibit 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. The control unit 18 controls the operation of, for example, the fan 46 (see FIG. 3). The control unit 18 is covered by a control cover (not shown) as a metal housing, for example.

Fig. 3 is a block diagram showing essential components of the washing water supply device and the deodorizing device of the present embodiment.

4 is a schematic perspective view showing the deodorizing device of the present embodiment.

5 is a schematic exploded view showing the deodorizing device of the present embodiment.

6 is a schematic cross-sectional view illustrating a specific example of the electrolytic bath of the present embodiment.

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 atmospheric release buffet breaker VB 30, A first flow path 32 leading to the cleaning nozzle 14, a second flow path 34 leading to the deodorizing device 16, an electromagnetic pump 36, and a flow regulation / flow path switching valve 38 . In addition, the washing water supply device 12 does not necessarily have the heat exchanger 26. The water supplied from the outside is sent to the electrolytic bath 28 through the heat exchanger 26 when the flow path opening / closing valve 24 is opened.

As shown in Fig. 6, the electrolytic bath 28 has a first electrode 28a and a second electrode 28b. The first electrode 28a is, for example, a positive electrode. The second electrode 28b is, for example, a cathode. The first electrode 28a and the second electrode 28b are formed inside the electrolytic bath 28. The electrolytic bath 28 can electrolyze the tap water flowing in the space between the first electrode 28a and the second electrode 28b based on the control signal of the energization transmitted from the control unit 18. [ In other words, the water sent to the electrolytic bath 28 is electrolyzed inside the electrolytic bath 28.

Tap water contains chlorine ion (Cl - ). Chlorine ions are contained as salt (NaCl), calcium chloride (CaCl 2 ), and the like in a source of water (for example, ground water, water in a dam or water in a river). Therefore, the reaction shown in the formula (1) occurs in the anode (for example, the first electrode 28a).

Cl - e - + 1 / 2Cl 2 (1)

The chlorine generated in the formula (1) is hardly present as bubbles, and most chlorine is dissolved in water. Therefore, the reaction shown in the formula (2) occurs for the chlorine generated in the formula (1).

Cl 2 + H 2 O → HClO + H + + Cl - (2)

Thus, hypochlorous acid (HClO) is produced by electrolyzing the chlorine ion. As a result, the electrolyzed water in the electrolytic bath 28 is changed to a liquid containing hypochlorous acid (hereinafter referred to as " functional water ").

The functional water generated by the electrolytic bath 28 flows into the first flow path 32 or the second flow path 34. [ The functional water flowing 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 repellent portion 15. For example, the water repellent portion 15 has a hip washing water jetting hole 15a, a hip soft jetting water hole 15b, a bidet washing water jetting hole 15c, and a wide bidet washing water jetting hole 15d. However, the water jet hole of the water jetting portion 15 is not limited to this. The functional water sent to the cleaning nozzle 14 is discharged upward from the water repellent portion 15. [ The function water discharged from the water jetting unit 15 is used for local cleaning of the user of the toilet flushing machine 2. [

A flow rate regulating / flow path switching valve 38 is provided between the electromagnetic pump 36 and the cleaning nozzle 14. The flow rate regulating and flow path switching valve 38 is operated to change the water flow rate, the water jet angle, and the water jet range of the functional water discharged from the cleaning nozzle 14. In addition, the function water can be sent to the nozzle washing chamber (body washing and cleaning section) 40 by operating the flow rate adjustment / flow path switching valve 38. The nozzle cleaning chamber (40) has a wedge portion (41). The nozzle cleaning chamber 40 cleans the outer surface of the cleaning nozzle 14, that is, cleans the body by discharging functional water from the water jetting portion 41.

The functional water flowing into the second flow path (34) is sent to the deodorizing device (16).

3 to 5, the deodorizing device 16 includes a dust collecting filter 44, a fan (blowing part) 46, a deodorizing filter 48, a spraying part 50, a water receiving part 52, and a filter case 72. As shown in Fig.

The water receiving portion (52) has an air inlet (42) and an air outlet (54). The inlet port (42) is provided in the inlet port section (21) of the case cover (10). The exhaust port 54 is provided in the exhaust port 22 of the case cover 10. The fan 46 is, for example, a sirocco fan made of resin. The fan 46 sucks air in the toilet room 100 from the inlet port 42 by rotating a plurality of vanes provided inside and discharges the sucked air from the air outlet 54 to the toilet room 100. Further, the fan 46 is not limited to a sirocco fan.

As shown in Fig. 4, the dust filter 44 is provided inside the first blade 68. The dust-collecting filter 44 prevents dust or dust in the air being sucked from being sent to the fan 46. The dust filter 44 can be separated from the deodorizing device 16 by separating the first wing plate 68 from the case cover 10. Therefore, the dust filter 44 can be easily separated from the sanitary washing apparatus 1. Accordingly, the dust filter 44 can be cleaned more easily. Further, the dust collecting filter 44 may be integrally formed with the first blade 68. In this case, the dust collecting filter 44 and the first wing plate 68 can be separated from the case cover 10 at the same time. Or the dust collecting filter 44 may be provided at a portion of the suction port 42.

The deodorization filter 48 has a porous structure. That is, the deodorization filter 48 has a porous structure.

As used herein, the term " porous structure " refers to a structure having a material density of 1 g / cm 3 and capable of maintaining water of 0.5 mL or more per g. In other words, in the present specification, the term " porous structure " refers to a cube having a weight of 1 g and a cube having a length of 1 cm and capable of holding water of 0.5 mL or more.

The material of the deodorization filter 48 includes ceramics. More specifically, the material of the deodorization filter 48 includes silica (SiO 2 ) and alumina (Al 2 O 3 ). More specifically, the deodorization filter 48 is a sintered body of silica and alumina. The deodorization filter 48 has a honeycomb structure. Specific examples of the honeycomb structure of the deodorization filter 48 will be described later. The deodorization filter 48 is held in the filter case 72.

The functional water is sprayed to the deodorization filter 48 by the spraying unit 50. The deodorization 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 provided on the upstream side of the deodorization filter 48 to which the functional water is sprayed. Therefore, air containing moisture can be prevented from being sent from the deodorization filter 48 to the fan 46. Therefore, the fan 46 can be prevented from failing due to moisture.

The air discharged from the fan (46) passes through the deodorization filter (48). Therefore, the air stagnated inside the sanitary washing apparatus 1 before the fan 46 operates necessarily passes through the deodorization filter 48 and is discharged to the toilet room 100 after the odorous components are collected. Therefore, when the fan 46 is operated, the air stagnated inside the sanitary washing apparatus 1 can be prevented from being discharged to the toilet room 100 without collecting or decomposing odorous components.

The deodorization filter 48 is freely withdrawable from the exhaust port 54 by the user's operation. More specifically, the deodorization filter 48 can be drawn out while being held by the filter case 72. The user can freely draw the deodorization filter 48 from the exhaust port 54 by separating the deodorization filter 48 from the filter case 72. [ The cleaning property of the deodorization filter 48 is improved.

The spraying section 50 has a solenoid valve and is formed above the deodorization filter 48. [ When the spraying section 50 is operated to open the valve by the control section 18, the functional water is sprayed from above the deodorization filter 48 toward the deodorization filter 48, for example, for about 3 seconds or more for about 5 seconds or less . The functional water is sprayed while expanding in a conical shape with the spraying portion 50 as a vertex. The diffusion angle of the functional water sprayed from the spraying portion 50 is about 110 degrees.

When the function water is sprayed toward the deodorization filter 48, the deodorization filter 48 maintains the function number. The diameter of the water sprayed from the spraying portion 50 is, for example, about 10 占 퐉 or more and 1000 占 퐉 or less. Therefore, the functional water sprayed from the spraying section (50) permeates the material of the deodorization filter (48) without forming a water film in the honeycomb structure of the deodorization filter (48). As used herein, the term "penetration" is intended to include not only that the liquid is permeated into the material but also that the liquid is retained in the pores of the porous structure.

When the fan 46 is operated, the air in the toilet room 100 sucked from the intake port 42 passes through the deodorization filter 48. Here, when the deodorization filter 48 keeps the functional water, if the air passes through the deodorization filter 48, the odor component contained in the air is introduced into the functional water. The odor component introduced into the function water is decomposed by the hypochlorous acid contained in the functional water as follows.

HClO + NH 3 → NH 2 Cl + H 2 O ··· (3)

As shown in equation (3), ammonia (NH 3 ) changes to monochloramine (NH 2 Cl) and water (H 2 O) by reacting with hypochlorous acid (HClO). The odor of monochloramine is the smell of Calc like chlorine. The odor of monochloramine allows the user to feel cleanliness. The odor components remaining after the decomposition are collected in the functional water. Therefore, it is possible to restrain the odor component remaining not decomposed from returning to the air. As a result, the air that has passed through the deodorization filter 48 is removed from the odor component.

The air from which the odor component is removed is discharged from the air outlet 54 to the toilet room 100. Thus, the deodorizing device 16 can collect or disassemble odorous components that are always present in the toilet room 100. Therefore, when the user enters the toilet room 100, the user does not have to suck the odor components always present in the toilet room 100, so that the user can comfortably use the toilet room 100.

According to the present embodiment, since the deodorization filter 48 has a porous structure, it is easy to maintain the functional water. Therefore, the sanitary washing apparatus 1 according to the present embodiment can ensure higher deodorizing performance. Further, since the functional water is a liquid containing hypochlorous acid, ammonia and trimethylamine can be decomposed with hypochlorous acid. Further, since the material of the deodorization filter 48 includes ceramics, the deodorization filter 48 has a constant hardness and can suppress deformation due to aged deterioration. Further, since the deodorization filter 48 is a sintered body of silica and alumina, corrosion due to functional water can be suppressed, and the deodorization filter 48 can be used for a longer period of time. Further, since the deodorization filter 48 has a honeycomb structure, the contact area between the air and the functional water in the toilet room 100 sucked from the inlet port 42 is wider. Therefore, the decomposition performance of odorous components such as ammonia can be improved.

As described above with reference to Figs. 1 and 2, the source of the odor component in the embodiment is the urine adhered to the floor or the wall of the toilet room 100, and the odor component in the bowl portion 20 of the toilet unit 2, . The deodorizing device 16 is easy to deodorize if the inlet port 42 of the deodorizing device 16 is installed in the inlet port portion 21 formed on the side surface or the rear surface of the case cover 10. [

The air discharged from the fan (46) passes through the deodorization filter (48) downwardly from above the deodorization filter (48). Accordingly, a stay such as scale or dust staying in the deodorization filter 48 can be dropped to the water receiving portion 52 by the air discharged from the fan 46 and the weight of the stay itself. Therefore, it is difficult for the retentate to stay in the deodorization filter 48.

The air discharged from the fan 46 may pass through the deodorization filter 48 from below the deodorization filter 48 toward the upward direction. In this case, the scale, dust, and the like stay in the lower portion of the deodorization filter 48 (the portion of the windward portion of the deodorization filter 48). On the other hand, the functional water is sprayed toward the deodorization filter 48 from above the deodorization filter 48. Accordingly, a stay such as scale or dust staying on the lower part of the deodorization filter 48 can be dropped from the spray part 50 to the water receiving part 52 by the sprayed functional water.

4 and 5, the water receiving portion 52 has a drain hole 56 opened toward the case plate 8. As shown in Fig. The bottom surface of the water receiving portion (52) is inclined toward the drain port (56). The functional water flowing into the water receiving portion 52 flows toward the water discharging opening 56 without staying on the bottom surface of the water receiving portion 52. [

Fig. 8 (a) is a schematic plan view showing the filter case when viewed in the direction of an arrow A31 shown in Fig. 5. Fig. 8 (b) is a schematic plan view showing the deodorization filter when viewed in the direction of the arrow A31 shown in Fig. 5. Fig. 8 (a) and 8 (b) are schematic plan views illustrating specific examples of the deodorizing filter and the filter case when viewed from above to below.

9 (a) is a schematic plan view showing a structure in which holes of a square column are arranged. 9 (b) is a schematic plan view showing a structure in which holes of a triangular column are arranged. 9 (c) is a schematic plan view showing a structure in which holes of a hexagonal column are arranged. 9 (a) to 9 (c) are schematic plan views showing an enlargement of the deodorization filter when viewed in the direction of the arrow A31 shown in Fig.

As shown in Fig. 7, the deodorization filter 48 is held in the filter case 72. Fig. 8 (a) and 8 (b), the length in the first direction (the transverse direction in Fig. 8 (a)) of the portion of the filter case 72 where the deodorization filter 48 is held D1 is longer than the length D3 of the deodorization filter 48 in the first direction. The length D2 of the portion of the filter case 72 where the deodorization filter 48 is held in the second direction (the longitudinal direction in FIG. 8A) corresponds to the length D4 of the deodorization filter 48 in the second direction ). That is, there is a gap between the deodorization filter 48 and the filter case 72 while the deodorization filter 48 is held in the filter case 72.

According to this, external force applied to the deodorization filter 48 can be dispersed, and even if the deodorization filter 48 is made of ceramic, the deodorization filter 48 can be prevented from being broken. For example, when the deodorization filter 48 is attached to the filter case 72 or the deodorization filter 48 is separated from the filter case 72, an external force may be applied to the deodorization filter 48. Even in this case, since there is a gap between the deodorization filter 48 and the filter case 72, the external force applied to the deodorization filter 48 can be dispersed and the deodorization filter 48 can be prevented from being broken.

The deodorization filter 48 has a honeycomb structure. In the specific example shown in Figs. 8 (b) and 9 (a), the deodorization filter 48 has a structure in which holes 48a of a quadrangular column are arranged. As in the specific example shown in Fig. 9 (b), the deodorization filter 48 of the present embodiment may have a structure in which the holes 48b of the triangular column are arranged. Or the deodorization filter 48 of the present embodiment may have a structure in which the holes 48c of the hexagonal column are arranged as in the specific example shown in Fig. 9 (c).

Thus, in the present specification, the "honeycomb structure" is not limited to a structure in which holes of a hexagonal column are arranged, but refers to a structure in which a three-dimensional figure such as a hole in a triangular column or a hole in a square column is arranged. Figs. 9 (a) to 9 (c) show a three-dimensional figure possessed by the honeycomb structure of the deodorization filter 48 when viewed downward from above.

The axis of the three-dimensional figure of the honeycomb structure of the deodorization filter 48 is parallel to the up-and-down direction. The axis of the solid figure of the honeycomb structure of the deodorization filter 48 refers to the axis of the hole of the quadrangular column in the specific example shown in Fig. 9 (a). The axis of the solid figure of the honeycomb structure of the deodorization filter 48 refers to the axis of the hole of the triangular column in the specific example shown in Fig. 9 (b). The axis of the solid figure of the honeycomb structure of the deodorization filter 48 refers to the axis of the hole of the hexagonal column in the specific example shown in Fig. 9 (c).

By this, the water is spread widely in the vertical direction of the deodorization filter 48. Therefore, substantially all of the deodorization filter 48 is in a state of holding water. Accordingly, the sanitary washing apparatus 1 according to the present embodiment can secure a higher deodorizing performance.

10 is a schematic plan view showing the interior of the sanitary washing apparatus according to the present embodiment.

The cleaning of the deodorizing filter of this embodiment will be described with reference to Fig.

As described above with reference to Figs. 3 to 6, the deodorizing device 16 of this embodiment captures or decomposes odorous components contained in the air by passing air through the deodorization filter 48 holding the functional water. As a result, the substance causing the odor is adsorbed by the deodorization filter 48. If the deodorization filter 48 is not maintained, the deodorization performance of the deodorization filter 48 may not be ensured.

On the other hand, the control unit 18 of this embodiment performs control to perform the cleaning operation of the deodorization filter 48. [ The controller 18 supplies the deodorization filter 48 with the function water of the deodorization filter 48 at a maximum flow rate or more at the non-use time of the user. The control unit 18 may supply the function water to the deodorization filter 48 a plurality of times during a predetermined time. In this case, the total amount of supply may be equal to or greater than the flow amount of the deodorization filter 48. Or the amount of each of the plural times supplied may be equal to or greater than the flow rate of the deodorization filter 48. The "predetermined time" is, for example, about one minute or longer and about 10 minutes or shorter. Details of the " non-use time zone " will be described later.

The maximum flow rate of the deodorization filter 48 is about 10 mL. When the deodorization filter 48 is to be cleaned, the spraying section 50 sprays about 100 mL or more and about 150 mL or less of functional water toward the deodorization filter 48. That is, the spraying section 50 can clean the deodorization filter 48 by spraying water at a maximum flow rate of the deodorization filter 48. Thus, odor components trapped in the deodorizing filter 48 before the spraying of the functional water can be washed away.

The functional water used for cleaning the deodorization filter 48 flows to the water receiving portion 52 located below the deodorization filter 48. [ The functional water flowing into the water receiving portion 52 is discharged from the drain port 56 of the water receiving portion 52 and is 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 ribs 58 protrude upward from the upper surface of the case plate 8 and form a discharge passage 60. The discharge passage 60 discharges the water that has passed through the deodorization filter 48. For example, the discharge flow path 60 discharges the functional water from which the deodorizing filter 48 is cleaned. The discharge passage 60 has a hole for discharging the bowl portion 62. The bowl portion discharge hole 62 is formed adjacent to the position where the nozzle cleaning chamber 40 is installed. The bowl portion discharge hole 62 is formed in the front portion of the case plate 8. The ribs 58 are installed in a line to guide the functional water discharged from the drain port 56 (see FIGS. 4 and 5) to the bowl discharge port 62.

The discharge passage 60 is inclined downward toward the front. Accordingly, the functional water discharged from the drain port 56 as shown by the arrows A21 to A27 shown in Fig. 10 flows in the discharge passage 60 toward the front according to the gravity. Accordingly, the function water discharged from the drain port 56 can be more easily guided to the bowl discharge hole 62.

The function water led to the bowl discharge opening 62 is discharged to the bowl portion 20 of the toilet 10. Accordingly, the functional water used for cleaning the deodorization filter 48, and the functional water that collected the odor component is discharged to the bowl portion 20. [ In the bowl portion 20, cleaning with water is frequently performed. Accordingly, it is possible to inhibit the user from feeling uncomfortable by suppressing the generation of odor due to drying of the area to which the functional water is attached.

The bore portion discharge hole 62 is adjacent to the position where the nozzle cleaning chamber 40 is installed. Therefore, when the nozzle cleaning chamber 40 carries out the cleaning of the cleaning nozzle 14, the functional water used for cleaning the cleaning nozzle 14 carries out a part of the discharge flow passage 60, ) To the bowl portion (20). That is, the functional water used for cleaning the cleaning nozzle 14 flows through a part of the discharge passage 60 through which the functional water discharged from the discharge port 56 of the water receiving portion 52 flows. As a result, a part of the discharge passage 60 and the bore discharge hole 62 are cleaned by the cleaning of the body of the cleaning nozzle 14. As a result, odor can be prevented from being generated from the discharge passage 60 and the hole for discharging the bowl portion 62 after the functional water collecting the odor component is dried, and the user can be prevented from feeling uncomfortable.

The cleaning nozzle 14 is disposed in a space between the case plate 8 and the case cover 10 to discharge functional water from all of the water jet holes of the water jetting section 15, (Self-cleaning). At this time, the portion of the water jetting portion 15 of the cleaning nozzle 14 is accommodated in the nozzle cleaning chamber 40. The functional water discharged from the water repellent portion 15 is reflected by the inner wall of the nozzle washing chamber 40 and is caught by the water repellent portion 15. Accordingly, the portion of the water repellent portion 15 is also cleaned by the function water reflected on the inner wall of the nozzle washing chamber 40.

The functional water used for self cleaning flows through a part of the discharge passage 60 and is discharged from the bore portion discharge hole 62 to the bowl portion 20. [ That is, the functional water used for the self-cleaning flows through a part of the discharge passage 60 through which the functional water discharged from the discharge port 56 of the water receiving portion 52 flows. As a result, a part of the discharge passage 60 and the hole for discharging the bowl portion 62 are cleaned by self-cleaning water. As a result, odor can be prevented from being generated from the discharge passage 60 and the hole for discharging the bowl portion 62 after the functional water collecting the odor component is dried, and the user can be prevented from feeling uncomfortable.

Since the hole 62 for discharging the bowl portion is adjacent to the position for installing the nozzle washing chamber 40, the discharging position of the functional water used for washing the deodorization filter 48 to the bowl portion 20 is set to the self- And is adjacent to the discharge position of the functional water used for cleaning the body of the cleaning nozzle 14 to the bowl portion 20. [ This makes it possible to prevent the user from recognizing that the sanitary washing apparatus 1 is malfunctioning when the number of functions used for cleaning the deodorization filter 48 is discharged to the bowl portion 20.

Next, a specific example of the operation of the sanitary washing apparatus according to the present embodiment will be described with reference to the drawings.

11 is a table for explaining a method of determining the frequency of use.

The control unit 18 of the present embodiment divides one day (24 hours) every 45 minutes to form 32 units, and the presence or absence of human body detection by the human body detection sensor 13 is stored. 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 " o " is written when the human body detecting sensor 13 detects a human body. On the other hand, when the human body detecting sensor 13 does not detect the human body, no symbol is written (no symbol).

The control unit 18 sums up the number of times the user detection sensor 13 detects the human body (the number of times the user uses the toilet room 100) over eight days in two neighboring units (90 minutes). If the total number of times in 90 minutes is 0 (zero), the control unit 18 sets the frequency of use in which the user sets the toilet room 100 to be the " unused time zone ". If the total number of times in 90 minutes is equal to or greater than 1 and less than 4, the control unit 18 sets the frequency of use in which the user sets the toilet room 100 to be " If the total number of times in 90 minutes is 4 or more, the control unit 18 sets the frequency of use in which the user sets the toilet room 100 to be the " use time zone ".

For example, in the two units (90 minutes) surrounded by the thick frame line shown in Fig. 11, the sum of the number of times the human body detecting sensor 13 detects the human body over 8 days is " 3 ". Therefore, the control unit 18 sets the frequency of use of the two units surrounded by the thick frame lines shown in Fig. 11 to " not used in a very short time period (small) ".

12 is a timing chart illustrating a specific example of the operation of the sanitary washing apparatus according to the present embodiment.

This embodiment is an example of a normal cleaning operation of the deodorization filter 48. [ In this specific example, more than eight days have elapsed since the user used the toilet room 100. The control unit 18 of the present embodiment controls the cleaning operation of the deodorization filter 48 in the first "unused time zone" in one day (24 hours). That is, the control unit 18 of the present embodiment controls the cleaning operation of the deodorization filter 48 at least once a day.

When the frequency of use reaches the " use time zone ", the control unit 18 starts the operation of the fan 46 and executes control to spray functional water from the spray unit 50 (timing t1). The spraying section 50 sprays about 12 mL or more and about 15 mL or less of functional water toward the deodorization filter 48 over a period of about 3 seconds to 5 seconds, for example. The deodorization filter 48 maintains the maximum number of functional water functions.

The odor component contained in the air sucked from the suction port portion 21 is collected or disassembled by the deodorizing device 16 because the fan 46 operates while the deodorization filter 48 keeps the function water. That is, the deodorizing operation by the deodorizing device 16 is executed. The deodorizing operation by the deodorizing device 16 is performed until the deodorizing filter 48 is dried.

In the present specification, " drying " of the deodorization filter 48 refers to a state in which the weight of the deodorization filter 48 inhaled or retained water is returned by the weight of the deodorization filter 48 before the water is sucked or held . The time taken for the deodorization filter 48 of the present embodiment to dry by the air sent from the fan 46 after the water having the maximum amount of water is held is about 30 minutes or more and about 2 hours or less.

Since the deodorization operation is performed until the deodorization filter 48 is dried, the deodorization filter 48 is dried when the deodorization operation is not performed. As a result, the propagation of bacteria such as fungi in the deodorization filter 48 can be suppressed.

When the deodorization filter 48 is dried, the control unit 18 performs control for spraying functional water from the spray unit 50 (timing t2). The spraying section 50 sprayes functional water of about 12 mL or more and 15 mL or less toward the deodorization filter 48 over a period of about 3 seconds to 5 seconds, for example. Accordingly, the deodorization filter 48 maintains the maximum flow amount of function.

Subsequently, when the frequency of use reaches the " unused time zone ", the control unit 18 executes control to stop the operation of the fan 46 (timing t3).

Subsequently, when the frequency of use reaches the " unused time zone ", the control unit 18 controls the cleaning operation of the deodorization 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 "unused time zone".

More specifically, the control unit 18 performs control for spraying the functional water from the spray unit 50 while the operation of the fan 46 is stopped (timing t4). The spraying section 50 sprays about 24 mL or more and 26 mL or less of functional water toward the deodorization filter 48 over about 5 seconds or more and 7 seconds or less, for example. Subsequently, when about one minute has elapsed since the spraying of the functional water has been completed, the spraying section 50 deodorizes the functional water of about 24 mL or more and 26 mL or less for about 5 seconds or more and 7 seconds or less, for example. And is sprayed again toward the filter 48. The spraying section 50 repeats this operation and sprays the functional water to the deodorization filter 48 a plurality of times (timing t4 to t5) within a predetermined time. In this specific example, the spraying unit 50 sprayes the functional water to the deodorization filter 48 six times in the cleaning operation of the deodorization filter 48, and collects the functional water, for example, about 150 mL in total, (48).

Subsequently, the control unit 18 starts the operation of the fan 46 for 45 minutes before the frequency of use is switched to the " use time zone ", and executes control to spray the functional water from the spray unit 50 (timing t6 ). When the deodorization filter 48 is dried, the control unit 18 performs control to spray functional water from the spray unit 50 (timing t7). At timing t6 and timing t7, the spraying section 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorization filter 48 over a period of about 3 seconds to 5 seconds, for example. Accordingly, the deodorization filter 48 maintains the maximum flow amount of function.

According to this, it is possible to remove the odor which is always present in the toilet room 100 before the time when the user is more likely to enter the toilet room 100. Therefore, it is possible to inhibit the user from feeling uncomfortable by sucking the odor which always exists in the toilet room 100.

According to this embodiment, the deodorization filter 48 for deodorizing the space of the toilet room 100 can be cleaned at the non-use time. Thus, the deodorization filter 48 can be cleaned more efficiently, and the deodorization filter 48 can be made maintenance free for a long period of time. In addition, by performing the cleaning operation of the deodorization filter 48 at the non-use time period, it is possible to suppress the possibility that the deodorization filter 48 is known to the user.

Further, since the cleaning operation of the deodorization filter 48 is performed at least once a day, the deodorization performance of the deodorization filter 48 can be ensured.

In addition, since the operation of the fan 46 is stopped during the cleaning operation of the deodorization filter 48, the spraying section 50 can spray functional water at an arbitrary position. For example, it is possible to prevent the function water sprayed from the spraying portion 50 from flowing out to the outside of the deodorizing device 16 or the outside of the sanitary washing apparatus 1.

The control unit 18 may reverse the polarity of the voltage applied between the electrodes of the electrolytic bath 28 every time the functional water is sprayed when performing the control for spraying the functional water from the spraying unit 50 a plurality of times (timing t4 ~ t5). For example, the controller 18 sets the first electrode 28a as an anode and the second electrode 28b as a cathode to generate and spray functional water, and then, in the generation and spraying of the next functional water, The first electrode 28a is set as the cathode and the second electrode 28b is set as the anode. Generation of a scale such as calcium carbonate (CaCO 3 ) can be suppressed by performing polarity reversal (pole change) in the cleaning operation of the deodorization filter 48. As a result, the electrolytic efficiency of the electrolytic bath 28 is lowered and the generation efficiency of the sterilizing water is prevented from being lowered. In addition, since the spraying section 50 sprayes the functional water a plurality of times, the time during which the flow path opening / closing valve 24 is opened can be suppressed, and heat generated in the circuit board or the like can be suppressed.

In the present embodiment, when the "unused time zone" of the frequency of use does not exist, the cleaning operation of the deodorization filter 48 has become the first unit among the 32 units that divide one day every 45 minutes . When there is no " unused time zone " in the usage frequency in this specific example, the cleaning operation of the deodorization filter 48 is executed when the use frequency becomes the first " . That is, in the specific example shown in Fig. 12, when the "unused time zone" of the frequency of use does not exist, the cleaning operation of the deodorization filter 48 may be started at timing t3.

The control of the cleaning operation of the deodorization filter 48 may be performed by a user's instruction. More specifically, the user may control the cleaning operation of the deodorization filter 48 by operating the operation unit 74 (see Fig. 1). According to this, the user can perform the cleaning operation of the deodorization filter 48 at an arbitrary timing.

13 is a timing chart illustrating another specific example of the operation of the sanitary washing apparatus according to the present embodiment.

This embodiment is an example in which the cleaning operation of the deodorization filter 48 is performed for the first time after the sanitary washing apparatus 1 is installed.

The control unit 18 does not control the cleaning operation of the deodorization filter 48 on the first day after the installation of the sanitary washing apparatus 1. The control unit 18 performs control of the cleaning operation of the deodorization filter 48 for the first time on the second day after the installation of the sanitary washing apparatus 1. For this reason, this embodiment is an example of the second day after installation of the sanitary washing apparatus 1. On the second day after the installation of the sanitary washing apparatus 1, the control unit 18 can execute the control of the specific example described above with reference to Fig. 12 as it is accumulating the data (the number of times of use) for setting the above- There is no.

Therefore, in this specific example, when the first unit of the 32 units is divided into 45 minutes for one day on the second day after installation of the sanitary washing apparatus 1, the controller 18 controls the cleaning operation of the deodorization filter 48 (Timing t11). That is, in this specific example, the " unused 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 in operation, the control unit 18 stops the operation of the fan 46 and controls the cleaning operation of the deodorization filter 48.

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

Subsequently, when the cleaning operation of the deodorization filter 48 is completed, the control unit 18 executes control to start the operation of the fan 46 (timing t12). The odor component contained in the air sucked from the inlet port portion 21 is collected or disassembled by the deodorizing device 16 because the fan 46 is operating with the deodorization filter 48 holding the functional water. That is, the deodorizing operation by the deodorizing device 16 is executed. 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 deodorization filter 48 is dried (timing t14).

14 is a timing chart illustrating still another specific example of the operation of the sanitary washing apparatus according to the present embodiment.

This embodiment is an example of the fifth day after installation of the sanitary washing apparatus 1. The control unit 18 is accumulating data (the number of times of use) for setting the use frequency described above with reference to Fig. Thus, the control unit 18 of this embodiment sets the frequency of use based on the data (the number of times of use) accumulated from the first day to the fourth day after the installation of the sanitary washing apparatus 1.

The control unit 18 executes control to start the operation of the fan 46 (timing t21) when it becomes the first unit among the 32 units that divides one day every 45 minutes. Subsequently, the control unit 18 performs control to spray functional water from the spraying unit 50 67.5 minutes before the frequency of use is switched to the " use time zone " (timing t22). When the deodorization filter 48 is dried, the control unit 18 performs control to spray functional water from the spray unit 50 (timing t23). At the timing t22 and the timing t23, the spraying unit 50 sprays about 12 mL or more and 15 mL or less of functional water toward the deodorization filter 48 for about 3 seconds or more and 5 seconds or less, for example. Accordingly, the deodorization filter 48 maintains the maximum flow amount of function.

According to this, it is possible to remove the odor which is always present in the toilet room 100 before the time when the user is more likely to enter the toilet room 100. Therefore, it is possible to inhibit the user from feeling uncomfortable by sucking the odor which is always present in the toilet room 100.

Subsequently, when the frequency of use reaches the " unused time zone ", the control unit 18 controls the cleaning operation of the deodorization 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 "unused time zone". The operation of the timings t24 to t25 is the same as the operation described above with respect to the timings t4 to t5 of the specific example shown in Fig.

Subsequently, the control unit 18 performs control to stop the operation of the fan 46 after the deodorization filter 48 is dried (timing t26).

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

Fig. 15 is a flowchart illustrating still another specific example of the operation of the sanitary washing apparatus according to the present 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 the 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 deodorization 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 performs the control of the cleaning operation of the deodorization filter 48, (Step S15). The cleaning operation of the deodorization filter 48 is the same as the operation described above with respect to the timings t4 to t5 in 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 passed a predetermined number of times (step S11). In this case, when the cumulative number of operations of the fan 46 has reached the predetermined number of times (step S11: Yes), the control unit 18 controls the cleaning operation of the deodorization filter 48 (step S13). On the other hand, when the cumulative number of operations of the fan 46 has not reached the predetermined number of times (step S11: No), the control unit 18 executes the control of the cleaning operation of the deodorization filter 48 46) (step S15). The cleaning operation of the deodorization filter 48 is the same as the operation described above with respect to the timings t4 to t5 in the specific example shown in Fig.

According to this embodiment, the deodorizing filter 48 can be cleaned according to the amount of air passing through the deodorization filter 48. [ Therefore, the deodorization performance of the deodorization filter 48 can be secured.
