Description

Aspects of the present invention generally relate to sanitary washing devices.

A sanitary cleaning device is known that releases ions into the toilet bowl to disinfect and deodorize the bowl (Patent Document 1).

JP 2014-36692 A

The sanitary washing device described in Patent Document 1 disinfects and deodorizes the inside of the toilet bowl, but there is a risk that it may be insufficient in suppressing dirt and odors in areas other than the toilet bowl.

The present invention was developed based on the recognition of these problems, and aims to provide a sanitary washing device with improved hygiene.

The first invention is a sanitary washing device comprising a casing, a local cleaning nozzle provided in the casing and extending toward the front of the casing, a functional gas generator provided in the casing for generating a functional gas that suppresses dirt, and a blower provided in the casing for generating an airflow that discharges the functional gas to the outside of the casing, the casing having an outlet for the local cleaning nozzle, and the functional gas being discharged from the outlet to the outside of the casing.

This sanitary washing device can improve hygiene by suppressing contamination of the outlet of the pubic washing nozzle. In addition, the functional gas discharged from the outlet can improve hygiene outside the casing (e.g., the toilet bowl or toilet room).

The second invention is a sanitary washing device according to the first invention, characterized in that the functional gas comes into contact with at least a portion of the local washing nozzle.

This sanitary washing device can reduce dirt on the genital washing nozzle and improve hygiene.

The third invention is a sanitary washing device according to the first invention, characterized in that the functional gas comes into contact with at least one of at least a portion of the inner surface of the casing located above the private parts washing nozzle and at least a portion of the bottom surface of the casing located below the private parts washing nozzle.

This sanitary cleaning device can reduce dirt on the inner surface and bottom of the casing, improving hygiene.

The fourth invention is a sanitary washing device according to the first invention, characterized in that it includes a cylindrical portion that houses the private parts washing nozzle therein, and the functional gas flows inside the cylindrical portion.

This sanitary cleaning device can reduce dirt buildup inside the tube, improving hygiene.

The fifth invention is a sanitary washing device according to the first invention, characterized in that it includes an extension plate portion located between the casing and the private parts washing nozzle and extending along the private parts washing nozzle, and the functional gas flows along at least a portion of the surface of the extension plate portion on which the private parts washing nozzle is located.

This sanitary cleaning device can reduce dirt on the extension plate and improve hygiene.

The sixth invention is a sanitary washing device according to the first invention, characterized in that the functional gas generator releases the functional gas behind the local cleaning nozzle, and the blower generates an air current that causes the functional gas to flow from behind the local cleaning nozzle toward the outlet.

This sanitary washing device allows the functional gas to efficiently come into contact with the private parts washing nozzle and the area around the private parts washing nozzle.

The seventh invention is the sanitary washing device according to the first invention, characterized in that the casing has an intake port that draws air from the toilet room into the inside when the blower is operated.

This sanitary washing device can prevent the functional gas discharged from the outlet of the local washing nozzle from being inhaled into the casing.

The eighth invention is a sanitary washing device according to the first invention, characterized in that the casing has a nozzle lid that covers the outlet in an openable and closable manner, and the functional gas generator releases the functional gas when the nozzle lid is open.

This sanitary cleaning device allows the functional gas to flow efficiently to the outlet of the local cleaning nozzle.

The ninth invention is the sanitary washing device of the eighth invention, characterized in that the nozzle cover is in an open state that is smaller than the fully open state.

This sanitary cleaning device allows the functional gas to flow efficiently to the outlet of the local cleaning nozzle. In addition, a large amount of functional gas can come into contact with the nozzle lid, preventing the nozzle lid from becoming dirty.

The tenth invention is the sanitary washing device of the eighth invention, further comprising a control unit for controlling the functional gas generator and the blower, and characterized in that the control unit executes a first mode in which the functional gas generator and the blower are operated with the nozzle lid opening angle set to a first angle, and a second mode in which the functional gas generator and the blower are operated with the nozzle lid opening angle set to a second angle larger than the first angle.

According to this sanitary washing device, in the first mode, the functional gas can be efficiently brought into contact with the private parts washing nozzle and its surroundings. On the other hand, in the second mode, the outlet opening of the private parts washing nozzle is enlarged, so that the functional gas can be efficiently brought into contact with the toilet bowl.

The eleventh invention is the sanitary washing device of the first invention, further comprising a control unit for controlling the functional gas generator and the blower, the control unit having a first mode and a second mode in which the output of the blower is different, and the output of the blower in the first mode is smaller than the output of the blower in the second mode.

According to this sanitary washing device, in the first mode, the output of the blower is reduced, so that more functional gas can remain in the private parts washing nozzle and its surroundings. This allows the functional gas to come into contact with the private parts washing nozzle and its surroundings efficiently. On the other hand, in the second mode, the output of the blower is increased, so that the functional gas can come into contact with the toilet bowl efficiently. Furthermore, by reducing the output of the blower in the first mode, power consumption can be reduced.

The twelfth invention is the sanitary washing device according to the tenth or eleventh invention, characterized in that the control unit sets the execution time of the first mode to be shorter than the execution time of the second mode.

This sanitary cleaning device changes the execution time to suit the space that the functional gas comes into contact with (the area around the pubic cleaning nozzle or inside the toilet bowl), so it can efficiently prevent contamination caused by the functional gas.

The thirteenth invention is the sanitary washing device according to the twelfth invention, further comprising a toilet lid rotatably mounted on the casing, and a toilet lid motor mounted on the casing for rotating the toilet lid between an open state and a closed state, the control unit further executes a third mode in which the functional gas generator and the blower are operated while the toilet lid is in the open state by the toilet lid motor, and the execution time of the third mode is longer than the execution time of the first mode.

With this sanitary washing device, the third mode can effectively prevent toilet room soiling.

The fourteenth invention is the sanitary washing device of the first invention, characterized in that the outlet has a front outlet that opens forward and a lower outlet that opens downward, and the casing has a nozzle lid that covers the front outlet in an openable and closable manner.

With this sanitary cleaning device, the functional gas can be efficiently directed toward the lower exhaust port even when the nozzle lid is closed. This can therefore reduce contamination of the outlet of the pubic cleaning nozzle and improve hygiene. In addition, the functional gas discharged from the outlet can improve hygiene outside the casing (e.g., the toilet bowl or toilet room).

According to the present invention, a sanitary washing device with improved hygiene can be provided.

Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 14. Figures 1 to 7 show a sanitary washing device according to a first embodiment of the present invention.
FIG. 1 is a perspective view showing a toilet apparatus equipped with a sanitary washing device according to a first embodiment of the present invention.
FIG. 2 is a front view of the toilet device in FIG. 1 .

The toilet device 1 shown in Figure 1 is installed in a toilet room TR. The toilet device 1 includes a Western-style seated toilet (hereinafter, for convenience of explanation, simply referred to as "toilet 100") and a sanitary washing device 10. As shown in Figures 1 and 2, the toilet 100 has a concave bowl portion 101 that receives waste. The sanitary washing device 10 is installed on top of the toilet 100.

The sanitary washing device 10 has a casing 12. The casing 12 is disposed behind the toilet bowl 100. The toilet seat 14 on which the user sits is rotatably attached to the casing 12. The toilet lid 16 is rotatably attached to the casing 12 so as to cover the toilet seat 14. In the states shown in Figures 1 and 2, the toilet seat 14 is closed (lowered) and the toilet lid 16 is open (raised). In this specification, "up," "down," "front," "back," "left," and "right" refer to the directions as seen by a user sitting on the toilet seat 14 with their back to the open toilet lid 16.

Inside the casing 12, there are provided a body washing function unit 58 that washes the body parts (such as the buttocks) of the user sitting on the toilet seat 14, a warm air unit 30 that dries the body parts of the user, and the like. In addition, inside the casing 12, there may be provided a spray device (not shown) that sprays sterilizing water toward the bowl portion 101.

In this embodiment, a functional gas generator 37 that generates functional gas S and a blower 39 that generates an air current for circulating the functional gas S are provided inside the casing 12. The functional gas generator 37 and the blower 39 will be described in detail later.

Figure 1 shows the state in which the private parts washing nozzle 58a (hereinafter referred to as nozzle 58a) of the body washing function unit 58 is advanced into the bowl portion 101. When the seating detection sensor 20 detects a user sitting on the toilet seat 14, the nozzle 58a can be advanced into the bowl portion 101 of the toilet 100 by the user operating the manual operation unit 26, such as a remote control.

The tip of the nozzle 58a is provided with one or more water outlets. The nozzle 58a can spray water from the water outlets at its tip toward the private parts of a user seated on the toilet seat 14, thereby cleaning the user's buttocks, etc.

When the user operates the toilet flushing function using a switch provided on the manual operation unit 26 (remote control) or when the user stands up from the toilet seat 14, a toilet flushing operation (an operation to expel waste from the bowl portion 101 and clean the inside of the bowl portion 101) is performed. In the toilet flushing operation, cleaning water is supplied into the bowl portion 101, and water is stored in the bowl portion 101.

FIG. 3 is a block diagram showing the configuration of the main parts of the sanitary washing device.
FIG. 3 shows the main configurations of the water channel system and the electrical system.

The seating detection sensor 20 can detect whether or not a user is seated on the toilet seat 14. The seating detection sensor 20 detects whether the user is sitting or leaving the seat. The seating detection sensor 20 is, for example, a contact sensor such as a tact switch, electrostatic sensor, or distortion sensor provided on the toilet seat 14.

When a user sits on the toilet seat 14, the user's weight presses the tactile switch. Alternatively, the user comes into contact with the electrostatic sensor. Alternatively, the user's weight applies pressure to the strain sensor. The electrical signals from these sensors can detect that the user is seated. The seating detection sensor 20 transmits the detection result to the control unit 28. The seating detection sensor 20 may also be a pyroelectric sensor or a distance measuring sensor (infrared sensor) provided in the casing 12.

The human body detection sensor 22 is provided, for example, in the casing 12, and detects a user (human body) approaching the toilet device 1. In other words, the human body detection sensor 22 detects a user in the vicinity of the toilet device 1. The human body detection sensor 22 can be, for example, a pyroelectric sensor, a microwave sensor, an ultrasonic sensor, or a distance sensor (infrared projector sensor).

The human body detection sensor 22 transmits the presence or absence of a human body to the control unit 28. The control unit 28 automatically opens the toilet lid 16 in response to, for example, the detection of a user by the human body detection sensor 22. Note that the human body detection sensor 22 only needs to be able to detect a user in the vicinity of the toilet device 1, and may be disposed, for example, in a cabinet provided to the side of the toilet device 1.

The toilet lid motor 24 is provided in the casing 12. The toilet lid motor 24 rotates the toilet lid 16 between an open state and a closed state. The toilet lid motor 24 is connected to the control unit 28, and opens and closes the toilet lid 16 in response to a command signal from the control unit 28.

The manual operation unit 26 is provided, for example, on a wall on the side of the toilet device 1. In other words, the manual operation unit 26 is a remote control having switches or buttons, and is operated by a user to activate various functional parts of the toilet device 1 (sanitary washing device 10). The manual operation unit 26 transmits a command signal based on the operation performed by the user to the control unit 28. The control unit 28 executes washing of the user's private parts and washing of the toilet bowl 100 based on the received command signal.

The hot air unit 30 dries the private parts of a user sitting on the toilet seat 14. The hot air unit 30 includes an air blower 32 and a hot air heater 34. The air blower 32 is, for example, a fan provided inside the casing 12. The air blower 32 operates based on a command signal from the control unit 28.

The blower 32 blows air from the outlet 12a provided on the front part of the casing 12 toward the inside of the toilet 100 (inside the bowl portion 101). As shown in FIG. 2, the outlet 12a is provided with a hot air drying lid 12b. The hot air drying lid 12b may be provided as necessary. The hot air heater 34 heats the air sent to the outside of the casing 12 by the blower 32. This allows hot air to be sent toward the user's private parts, drying them.

The functional gas unit 35 is provided in the casing 12. The functional gas unit 35 uses functional gas to suppress mold, bacteria, viruses, and the like in the nozzle 58a, the area around the nozzle 58a, the bowl portion 101, and the toilet room TR. In this way, the functional gas unit 35 improves the hygiene of the toilet device 1 and the toilet room TR. The functional gas unit 35 is equipped with a functional gas generator 37 and a blower 39.

The functional gas generator 37 is provided in the casing 12 and generates a functional gas S that suppresses dirt. Here, the functional gas S is a gas that contains, for example, ions, ozone, OH radicals, etc. Examples of the functional gas S include Plasmacluster (registered commercial product) and Nanoe (registered trademark).

In other words, the functional gas S suppresses the growth and proliferation of mold, bacteria, viruses, etc. floating in the air, and mold, bacteria, viruses, etc. attached to the casing 12 and the nozzle 58a. The functional gas generator 37 is connected to the control unit 28 and operates based on a command signal from the control unit 28.

The blower 39 is provided in the casing 12 and generates an air current that expels the functional gas S to the outside of the casing 12. The blower 39 is, for example, a fan, and is connected to the control unit 28. The blower 39 operates based on a command signal from the control unit 28. The blower 39 generates an air current that guides the functional gas S toward the nozzle storage section 13, the nozzle 58a, the bowl section 101, and the toilet room TR, which will be described later. A detailed explanation of the operation of the functional gas unit 35 and the flow state of the functional gas S will be given later.

In the waterway system, the sanitary washing device 10 has pipes 40-42, a solenoid valve 50, a vacuum breaker 52, a switching valve 56, a nozzle 58a, and a nozzle washing section 58c. These are arranged inside the casing 12.

The pipe 40 is for directing water supplied from a water supply source W, such as a waterworks or a water tank, to the nozzle 58a, the nozzle cleaning section 58c, etc. An electromagnetic valve 50 is provided upstream of the pipe 40. The electromagnetic valve 50 is an electromagnetic valve that can be opened and closed, and controls the supply of water based on commands from the control section 28 provided inside the casing 12.

A vacuum breaker 52 is provided on the pipeline 40 downstream of the solenoid valve 50. This vacuum breaker 52 has, for example, a flow path for flowing water, an air intake port for taking in air into the flow path, and a valve mechanism for opening and closing the air intake port. For example, the valve mechanism closes the air intake port when water is flowing in the flow path, and opens the air intake port when the water flow stops, taking in air into the flow path. In other words, the vacuum breaker 52 takes in air when there is no water flow in the pipeline 40. For example, a float valve is used as the valve mechanism.

By drawing air into the pipeline 40 as described above, the vacuum breaker 52 promotes drainage of water, for example, from the portion of the pipeline 40 downstream of the vacuum breaker 52. The vacuum breaker 52 promotes drainage of water, for example, from the nozzle 58a.

Downstream of the vacuum breaker 52 on the pipeline 40, a sterilization device 54 is provided that produces functional water (sterilized water). The sterilization device 54 produces sterilized water that contains, for example, hypochlorous acid. An example of the sterilization device 54 is an electrolytic cell unit. The electrolytic cell unit electrolyzes the water flowing through the space (flow path) between an anode plate (not shown) and a cathode plate (not shown) by controlling the flow of electricity from the control unit 28.

The disinfectant water is not limited to water containing hypochlorous acid. The disinfectant water may be, for example, a solution containing metal ions such as silver ions or copper ions, a solution containing electrolytic chlorine or ozone, acidic water or alkaline water. The disinfectant device 54 is not limited to an electrolytic cell, and may be any configuration capable of producing disinfectant water.

A switching valve 56 is provided downstream of the sterilization device 54 on the pipe 40. Downstream of the switching valve 56, the nozzle 58a and the nozzle cleaning section 58c of the body cleansing function section 58 are provided. The switching valve 56 branches the pipe 40 into a pipe 41 that guides water to the nozzle 58a and a pipe 42 that guides water to the nozzle cleaning section 58c.

The switching valve 56 controls the opening and closing of the pipe 41 or the pipe 42 based on a command from the control unit 28. In other words, the switching valve 56 controls the supply of water to the nozzle 58a or the nozzle cleaning unit 58c. The switching valve 56 also changes the flow rate of water supplied downstream.

The body cleansing function unit 58 has a nozzle 58a, a nozzle motor 58b, and a nozzle cleaning unit 58c. When not in use, the nozzle 58a is located behind the nozzle lid 13d (described below) and is provided inside the casing 12. When cleaning a private part of the human body, the nozzle 58a receives a driving force from the nozzle motor 58b and presses the nozzle lid 13d, which can be opened and closed relative to the casing 12, and advances into the bowl portion 101 of the toilet 100.

The nozzle motor 58b operates based on a command signal from the control unit 28. When the nozzle 58a advances forward from the casing 12, it ejects water from the water outlet to clean the human body parts. The nozzle cleaning unit 58c sprays sterilized water or water from an injection port provided inside it to clean the outer surface (body) of the nozzle 58a.

The control unit 28 is provided inside the casing 12 and uses a circuit that receives power from a power supply circuit (not shown). The control unit 28 includes an integrated circuit such as a microcomputer. The control unit 28 controls the functional gas generator 37 and the blower 39. The control unit 28 also controls the toilet lid motor 24, the blower 32, the hot air heater 34, the solenoid valve 50, the vacuum breaker 52, the sterilization device 54, the switching valve 56, and the nozzle motor 58b based on a command signal sent from the manual operation unit 26.

The control unit 28 receives detection information from the human body detection sensor 22 (a signal indicating whether or not a user is present) and detection information from the seating detection sensor 20 (a signal indicating whether or not a user is seated), and controls the operation of each part of the sanitary washing device 10 based on the received detection information.

The control unit 28 has a dirt suppression process that operates the functional gas unit 35 to suppress dirt. The dirt suppression process has, for example, a first mode to a third mode. The first mode is executed with the main purpose of suppressing dirt on the nozzle 58a and the nozzle storage section 13. The second mode is executed with the main purpose of suppressing dirt on the bowl section 101 of the toilet 100. The third mode is executed with the main purpose of suppressing dirt on the toilet room TR. The first to third modes will be explained in detail later.

Next, the flow path of the functional gas S in the first mode will be described with reference to FIGS.
FIG. 4 is an explanatory diagram showing a flow path of gas caused by a blower.
FIG. 5 is a cross-sectional view showing the flow of the functional gas in the first mode.

First, as shown in Figures 1 and 4, the casing 12 has an intake port 12c that draws air from the toilet room TR into the inside when the blower 39 is operated. The intake port 12c connects the inside and outside of the casing 12. In this example, the intake port 12c is provided on the left side surface of the casing 12.

The intake port 12c may be provided on the rear or top surface of the casing 12. The position of the intake port 12c is arbitrary as long as it can draw air from the toilet room TR into the inside of the casing 12. In other words, the intake port 12c is provided on the outer surface of the casing 12 that is exposed to the toilet room TR. By drawing air from the toilet room TR into the inside of the casing 12, it is possible to reduce the amount of functional gas S released into the bowl portion 101 being drawn back into the casing 12.

The casing 12 also has a nozzle storage section 13 that stores the nozzle 58a. The nozzle storage section 13 has an inner surface 13a of the casing 12 located above (directly above) the nozzle 58a, a bottom surface 13b of the casing 12 located below the nozzle 58a, and an outlet 13c of the nozzle 58a. The inner surface 13a is the part that overlaps with the nozzle 58a when viewed from above, for example. The bottom surface 13b is between the outlet 13c and the part that overlaps with the nozzle 58a when viewed from above, for example.

The nozzle storage section 13 is provided with a nozzle support section 59 that supports the nozzle 58a. The nozzle support section 59 is provided on the bottom surface 13b. A nozzle cleaning section 58c is provided on the front end side of the nozzle support section 59.

As shown in FIG. 2, the outlet 13c is provided on the front part of the casing 12. The outlet 13c is located below the toilet seat 14 when the toilet seat 14 is closed. The casing 12 has a nozzle lid 13d that covers the outlet 13c in an openable and closable manner. In other words, the nozzle storage section 13 has a nozzle lid 13d that covers the outlet 13c in an openable and closable manner. As shown in FIG. 5, in this example, the front end of the bottom surface 13b extends to a position close to the lower end of the nozzle lid 13d (the front part of the casing 12). Therefore, when the nozzle lid 13d is in a closed state, the entire outlet 13c is covered.

As shown in FIG. 5, the nozzle lid 13d can rotate forward with its upper end as a fulcrum. The upper end of the nozzle lid 13d serves as a fulcrum, and the lower end is a free end. The nozzle lid 13d rotates when pressed by the nozzle 58a. The nozzle lid 13d may be opened and closed by a motor, solenoid, or the like.

Here, the outlet 13c is a portion where, for example, sterilizing water or water used to clean the nozzle 58a is likely to remain. As a result, the outlet 13c is a portion where bacteria are likely to grow due to the remaining water.

As shown in Figures 4 and 5, the airflow Fs containing the functional gas S is discharged from the outlet 13c to the outside of the casing 12. This allows the functional gas S to come into contact with the outlet 13c, suppressing mold, bacteria, viruses, and the like that have adhered to the outlet 13c. This makes it possible to provide a sanitary washing device 10 with improved hygiene.

As shown in Figures 4 and 5, the functional gas generator 37 releases the functional gas S behind the nozzle 58a. The blower 39 generates an airflow Fs that causes the functional gas S to flow from behind the nozzle 58a toward the outlet 13c.

As a result, the airflow Fs containing the functional gas S comes into contact with at least a portion of the nozzle 58a. Therefore, the functional gas S can suppress mold, bacteria, and viruses that have adhered to the nozzle 58a before the airflow Fs flows toward the outlet 13c. The functional gas S can also suppress mold, bacteria, and viruses floating in the air. Therefore, the functional gas S can improve hygiene within the nozzle storage section 13 by the airflow Fs flowing through the nozzle storage section 13.

Furthermore, the airflow Fs containing the functional gas S contacts at least one of at least a portion of the inner surface 13a of the casing 12 located above the nozzle 58a and at least a portion of the bottom surface 13b of the casing 12 located below the nozzle 58a. The airflow Fs may contact all of the inner surface 13a and the bottom surface 13b, or may contact at least a portion of them. The airflow Fs may contact only at least a portion of the inner surface 13a without contacting the bottom surface 13b. The airflow Fs may also contact only at least a portion of the bottom surface 13b without contacting the inner surface 13a.

For example, the front end side (exit 13c side) of the inner surface 13a and the front end side of the bottom surface 13b are prone to residual water such as sterilizing water and water used to clean the nozzle 58a, making them areas that are easily soiled. On the other hand, the rear end sides of the inner surface 13a and the bottom surface 13b are areas that are less likely to become soiled than the front end sides.

Therefore, for example, the airflow Fs may flow so as to come into contact with at least the front end side (the outlet 13c side) of the inner surface 13a and the front end side of the bottom surface 13b. The flow path of the airflow Fs can be set based on the dirt distribution obtained through experiments, simulations, etc. In addition, the functional gas S also comes into contact with the rear surface of the nozzle lid 13d. By bringing the airflow Fs into contact with such parts that are easily soiled, it is possible to suppress the adhesion of mold, bacteria, and viruses.

In addition, by circulating the airflow Fs inside the nozzle storage section 13, the functional gas S can also come into contact with the nozzle support section 59 and the nozzle cleaning section 58c. This makes it possible to suppress mold, bacteria, and viruses that have adhered to the nozzle support section 59 and the nozzle cleaning section 58c.

Here, the functional gas generator 37 may release the functional gas S with the nozzle lid 13d open. Specifically, the control unit 28 advances the nozzle 58a and opens the nozzle lid 13d. The control unit 28 then operates the functional gas generator 37 and the blower 39. This increases the opening area of the outlet 13c, making it possible to efficiently guide the airflow Fs from within the nozzle storage unit 13 toward the outlet 13c. As a result, the functional gas S can be efficiently brought into contact with the nozzle storage unit 13, which is a part that is prone to becoming dirty.

In this case, it is preferable that the nozzle lid 13d be in a smaller open state than the fully open state. If the nozzle lid 13d were in a fully open state (as shown in FIG. 6), the opening area of the outlet 13c would be large, and there would be a risk that more airflow Fs would be discharged without contacting the nozzle lid 13d. Therefore, as shown in FIG. 5, the control unit 28 advances the nozzle 58a slightly to set the nozzle lid 13d in a smaller open state than the fully open state. This allows more airflow Fs to flow along the back surface of the nozzle lid 13d, so that mold, bacteria, and viruses adhering to the back surface of the nozzle lid 13d can be efficiently suppressed.

Next, with reference to FIG. 6, the flow path of the functional gas S in the second and third modes will be described.
FIG. 6 is a cross-sectional view showing the flow of the functional gas in the second mode and the third mode.

The second mode is executed primarily for the purpose of suppressing soiling of the bowl portion 101 of the toilet 100. For that reason, in the second mode, the opening angle of the nozzle lid 13d is set larger than in the first mode.

The control unit 28 executes a first mode in which the functional gas generator 37 and the blower 39 are operated with the nozzle lid 13d at an opening angle of a first angle (as shown in FIG. 5), and a second mode in which the functional gas generator 37 and the blower 39 are operated with the nozzle lid 13d at an opening angle of a second angle larger than the first angle (as shown in FIG. 6).

As shown in FIG. 6, the control unit 28 makes the extension dimension of the nozzle 58a larger than in the first mode. This causes the opening angle of the nozzle lid 13d to be larger in the second mode than in the first mode. As a result, the opening area of the outlet 13c is larger in the second mode than in the first mode.

Therefore, a large amount of airflow Fs containing the functional gas S can be discharged from the outlet 13c toward the bowl portion 101. In the second mode, it is preferable to operate the toilet lid motor 24 to close the toilet lid 16. This makes it possible to create a closed space inside the bowl portion 101, so that the airflow Fs discharged into the bowl portion 101 can efficiently come into contact with the bowl portion 101, the toilet seat 14, and the toilet lid 16. Therefore, mold, bacteria, and viruses adhering to the bowl portion 101, the toilet seat 14, and the toilet lid 16 can be suppressed. In addition, the airflow Fs can also suppress mold, bacteria, and viruses floating in the bowl portion 101.

The control unit 28 may also cause the output of the blower 39 to differ between the first mode and the second mode. In this case, the output of the blower 39 in the first mode is set to be smaller than the output of the blower 39 in the second mode. As a result, in the first mode, the wind speed (air volume) of the blower 39 is reduced, so that the air flow Fs remaining in the nozzle storage section 13 increases, and the concentration of the functional gas S in the nozzle storage section 13 can be increased. On the other hand, in the second mode, the wind speed (air volume) of the blower 39 is increased, so that a large amount of the functional gas S can be discharged from the outlet 13c to the bowl section 101.

The nozzle storage section 13 has a smaller space than the bowl section 101. Therefore, the control section 28 may set the execution time of the first mode to be shorter than the execution time of the second mode. This makes it possible to efficiently suppress mold, bacteria, and viruses in the nozzle storage section 13 and the bowl section 101 without operating the functional gas unit 35 more than necessary, and also to conserve power.

The third mode is executed primarily for the purpose of suppressing dirt in the toilet room TR. In the third mode, the airflow Fs containing the functional gas S is diffused into the toilet room TR to suppress mold, bacteria, and viruses floating in the toilet room TR.

In the third mode, the toilet lid motor 24 is operated to open the toilet lid 16. Other conditions are the same as those in the second mode. That is, when executing the third mode, the control unit 28 operates the toilet lid motor 24, and then operates the functional gas generator 37 and the blower 39. As a result, the airflow Fs containing the functional gas S is discharged from the outlet 13c through the bowl portion 101 into the toilet room TR. As a result, mold, bacteria, and viruses floating in the toilet room TR can be suppressed, thereby improving the hygiene of the toilet room TR.

In this case, the space of the toilet room TR is larger than the space of the nozzle storage section 13 and the space of the bowl section 101. Therefore, the execution time of the third mode may be longer than the execution time of the first mode. Also, the execution time of the third mode may be longer than the execution time of the second mode. In other words, the execution time of each mode may be the shortest in the first mode and the longest in the third mode. This makes it possible to efficiently suppress mold, bacteria, and viruses in the nozzle storage section 13, the bowl section 101, and the toilet room TR without operating the functional gas unit 35 more than necessary, and to achieve power saving.

The control unit 28 may also vary the output of the blower 39 in the first mode, second mode, and third mode. In this case, the output of the blower 39 in the third mode is made greater than the output of the blower 39 in the first mode and the second mode. This increases the wind speed (air volume) of the blower 39 in the third mode, so that more airflow Fs is diffused into the toilet room TR. This makes it possible to suppress mold, bacteria, and viruses over a wide area of the toilet room TR.

Figure 7 is a time chart showing an example of when the first to third modes are executed.

First, at time t0, the user seated on the toilet seat 14 operates the manual operation unit 26 to end the local cleansing. This causes the control unit 28 to store the nozzle 58a, which had advanced into the bowl portion 101, inside the casing 12 (inside the nozzle storage portion 13). When the nozzle 58a is stored, the control unit 28 executes the functional water mode. In the functional water mode, sterilizing water (functional water) or water is sprayed from the nozzle cleaning portion 58c to clean and sterilize the nozzle 58a.

At time t1, the functional water mode is terminated. When the control unit 28 terminates the functional water mode, it executes the first mode of the stain suppression process. In this example, when the first mode is being executed, the toilet lid 16 is in an open state. However, the control unit 28 may also close the toilet lid 16. In other words, in the first mode, the toilet lid 16 may be in either an open or closed state. By executing the first mode, mold, bacteria, and viruses in the nozzle storage unit 13 can be effectively suppressed.

At time t2, the first mode is ended. When the control unit 28 ends the first mode, it executes the second mode of the soil suppression process. First, the control unit 28 closes the toilet lid 16, which is in the open state. Then, the control unit 28 advances the nozzle 58a further from the state shown in FIG. 5 to the state shown in FIG. 6. The control unit 28 may increase the output of the blower 39. By executing the second mode, mold, bacteria, and viruses in the bowl portion 101 can be effectively suppressed.

At time t3, the second mode is ended. After ending the second mode, the control unit 28 executes the third mode of the soil suppression process. First, the control unit 28 opens the toilet lid 16, which is in a closed state. The control unit 28 may further increase the output of the blower 39. By executing the third mode, mold, bacteria, and viruses in the toilet room TR can be effectively suppressed.

At time t4, the third mode is ended. When the control unit 28 ends the third mode, it closes the toilet lid 16, which is in an open state. As shown in FIG. 7, the execution time of the first mode (from time t1 to time t2) is shorter than the execution time of the second mode (from time 2 to time t3) and the execution time of the third mode (from time t3 to time t4). Furthermore, the execution time of the second mode (from time 2 to time t3) is shorter than the execution time of the third mode (from time t3 to time t4). In this way, by executing the first to third modes, mold, bacteria, and viruses in the toilet device 1 and the toilet room TR can be effectively suppressed, and a deodorizing effect can be obtained.

For example, when the control unit 28 receives a human body detection signal from the human body detection sensor 22 while the soiling suppression process (first to third modes) is being performed, the control unit 28 stops the soiling suppression process. This makes it possible to prevent the soiling suppression process from being performed when a user is using the toilet device 1.

In this example, the first to third modes are executed consecutively after the end of local cleaning. However, the first to third modes can be executed arbitrarily. For example, the first to third modes may be executed at a preset time, or at preset time intervals. In addition, the first to third modes may be executed by the user or cleaner operating the manual operation unit 26 or a mobile terminal, for example.

Next, a sanitary washing device according to a second embodiment of the present invention will be described with reference to Figures 8 and 9. In the sanitary washing device according to the second embodiment, a nozzle is housed inside a cylindrical portion. In the second embodiment, the same components as those in the first embodiment described above are denoted by the same reference numerals, and their description will be omitted.
FIG. 8 is an explanatory view similar to FIG. 4, showing a sanitary washing device according to a second embodiment of the present invention.
Fig. 9 is a cross-sectional view showing the flow of functional gas in a sanitary washing device according to a second embodiment of the present invention, similar to Fig. 5. Fig. 9 shows the state of the first mode of the contamination suppression process.

The sanitary washing device 10 has a tubular portion 60 that houses the nozzle 58a. The tubular portion 60 is provided inside the casing 12. The tubular portion 60 has a front opening 60a at its front end and a rear opening 60b at its rear end. The tubular portion 60 is disposed so as to incline obliquely upward from the outlet 13c toward the rear.

The cylindrical portion 60 supports the nozzle 58a inside. The cylindrical portion 60 constitutes a part of the nozzle storage portion. In this example, the nozzle storage portion has the cylindrical portion 60, the outlet 13c of the nozzle 58a, and the nozzle lid 13d.

A nozzle lid 13d is disposed in front of the tube portion 60. The front opening 60a of the tube portion 60 may be located at the outlet 13c. In other words, the nozzle lid 13d may close the front opening 60a of the tube portion 60.

The functional gas unit 62 has a functional gas generator 63 and a blower 64. As shown in FIG. 9, the functional gas generator 63 releases the functional gas S behind the nozzle 58a. The blower 64 generates an airflow F that causes the functional gas S to flow from the rear of the nozzle 58a toward the outlet 13c. In this example, the functional gas S is released behind the rear opening 60b of the tube portion 60, and the airflow F is generated. The functional gas generator 63 and the blower 64 may be provided inside the tube portion 60.

As a result, the airflow Fs containing the functional gas S flows inside the tubular portion 60 from the rear opening 60b of the tubular portion 60 toward the front opening 60a. The airflow Fs then passes through the front opening 60a of the tubular portion 60 and is discharged from the outlet 13c to the outside of the casing 12. Therefore, the airflow Fs can suppress mold, bacteria, and viruses on the inner surface of the tubular portion 60, the nozzle 58a, the outlet 13c, and the nozzle cover 13d. Note that the second and third modes of the contamination suppression process are controlled in the same manner as in the first embodiment described above.

Next, sanitary washing devices according to third and fourth embodiments of the present invention will be described with reference to Figures 10 and 11. The sanitary washing devices according to the third and fourth embodiments have an extension plate between the nozzle and the casing. Note that in the third and fourth embodiments, the same components as those in the first embodiment described above are denoted by the same reference numerals, and their description will be omitted.
FIG. 10 is an explanatory view similar to FIG. 5, showing a sanitary washing device according to a third embodiment of the present invention.
FIG. 11 is an explanatory view similar to FIG. 5, showing a sanitary washing device according to a fourth embodiment of the present invention.
10 and 11 show the first mode of the stain suppression process.

As shown in FIG. 10, the extension plate portion 66 is located between the casing 12 and the nozzle 58a. Specifically, the extension plate portion 66 is located between the nozzle 58a and the inner surface 13a of the casing 12 located above the nozzle 58a. The extension plate portion 66 extends along the nozzle 58a. The extension plate portion 66 is disposed so as to incline obliquely upward from the upper end side of the outlet 13c toward the rear.

The extension plate portion 66 supports the nozzle 58a from above. In other words, the nozzle 58a is located on the lower surface 66a side of the extension plate portion 66. The nozzle 58a moves in the front-rear direction along the extension plate portion 66. In this example, the nozzle storage portion has the lower surface 66a of the extension plate portion 66, the bottom surface 13b of the casing 12, the outlet 13c, and the nozzle lid 13d.

The functional gas unit 67 has a functional gas generator 68 and a blower 69. The functional gas generator 68 emits the functional gas S behind the nozzle 58a. The blower 69 generates an airflow F that causes the functional gas S to flow from the rear of the nozzle 58a toward the outlet 13c. In this example, the functional gas S is emitted behind the rear end of the extension plate portion 66, and the airflow F is also generated.

As a result, the airflow Fs containing the functional gas S flows over at least a portion of the surface of the extension plate portion 66 on which the nozzle 58a is located (in this example, the lower surface 66a). The airflow Fs then contacts the lower surface 66a of the extension plate portion 66, the bottom surface 13b of the casing 12, the nozzle 58a, the outlet 13c, and the nozzle cover 13d. As in the first embodiment described above, the airflow Fs may be configured to contact at least parts that are easily soiled, such as the front end side of the lower surface 66a of the extension plate portion 66 and the front end side of the bottom surface 13b of the casing 12.

Therefore, the airflow Fs can suppress mold, bacteria, and viruses on the lower surface 66a of the extension plate portion 66, the bottom surface 13b of the casing 12, the nozzle 58a, the outlet 13c, and the nozzle lid 13d. Note that the second and third modes of the contamination suppression process are controlled in the same manner as in the first embodiment described above.

As shown in FIG. 11, the extension plate portion 70 is located between the casing 12 and the nozzle 58a. Specifically, the extension plate portion 70 is located between the nozzle 58a and the bottom surface 13b of the casing 12 located below the nozzle 58a. The extension plate portion 70 extends along the nozzle 58a. The extension plate portion 70 is disposed so as to incline obliquely upward from the lower end side of the outlet 13c toward the rear.

The extension plate portion 70 supports the nozzle 58a from below. In other words, the nozzle 58a is located on the upper surface 70a side of the extension plate portion 70. The nozzle 58a moves in the front-rear direction along the extension plate portion 70. In this example, the nozzle storage portion has the upper surface 70a of the extension plate portion 70, the inner surface 13a of the casing 12 located above the nozzle 58a, the outlet 13c, and the nozzle lid 13d.

The functional gas unit 71 has a functional gas generator 72 and a blower 73. The functional gas generator 72 emits the functional gas S behind the nozzle 58a. The blower 73 generates an airflow F that causes the functional gas S to flow from the rear of the nozzle 58a toward the outlet 13c. In this example, the functional gas S is emitted behind the rear end of the extension plate portion 70, and the airflow F is generated.

As a result, the airflow Fs containing the functional gas S flows over at least a portion of the surface of the extension plate portion 70 where the nozzle 58a is located (in this example, the upper surface 70a). The airflow Fs then comes into contact with the upper surface 70a of the extension plate portion 70, the inner surface 13a of the casing 12, the nozzle 58a, the outlet 13c, and the nozzle cover 13d. As in the first embodiment described above, the airflow Fs may come into contact with at least parts that are easily soiled, such as the front end side of the upper surface 70a of the extension plate portion 70 and the front end side of the inner surface 13a of the casing 12.

Therefore, the airflow Fs can suppress mold, bacteria, and viruses on the upper surface 70a of the extension plate portion 70, the inner surface 13a of the casing 12, the nozzle 58a, the outlet 13c, and the nozzle lid 13d. Note that the second and third modes of the contamination suppression process are controlled in the same manner as in the first embodiment described above.

FIG. 12 is a cross-sectional view showing the state of the third mode executed by the sanitary washing device according to the first modified example of the present invention.
In the above embodiment, the nozzle lid 13d is described as having the upper end side as the pivot point. However, the present invention is not limited to this, and may have a nozzle lid 80 having the lower end side as the pivot point, as in the first modified example shown in Fig. 12. In this case, the nozzle lid 80 may have a double-opening structure in which both the upper end side and the lower end side serve as pivot points.

The nozzle lid 80 can be realized as a double-opening structure by, for example, a motor or a solenoid. In addition, for example, there may be two pressing members (e.g., a nozzle for buttocks only and a nozzle for bidet only) that press the nozzle lid 80. In this case, one pressing member can press the upper end side of the nozzle lid 80 to realize an open state with the lower end side of the nozzle lid 80 as the pivot point. In addition, the other pressing member can press the lower end side of the nozzle lid 80 to realize an open state with the upper end side of the nozzle lid 80 as the pivot point.

As shown in FIG. 12, for example, in the third mode, the nozzle lid 80 may be in an open state with the lower end side thereof as the pivot point. This allows the airflow Fs to be discharged upward from the outlet 13c along the nozzle lid 80. Therefore, the airflow Fs can be efficiently diffused into the toilet room TR. On the other hand, in the second mode, the nozzle lid 80 may be in an open state with the upper end side thereof as the pivot point. This allows the airflow Fs to be discharged downward from the outlet 13c along the nozzle lid 80. Therefore, the airflow Fs can be efficiently diffused into the bowl portion 101.

FIG. 13 is a front view showing a nozzle cover of a sanitary washing device according to a second modified example of the present invention.
In the above embodiment, the hot air drying cover 12b and the nozzle cover 13d are provided separately. However, the present invention is not limited to this. For example, as in a second modified example shown in Fig. 13, a common cover 82 may be provided to cover both the outlet 13c of the nozzle 58a and the hot air drying outlet 12a.

In such a case, for example, when performing the first to third modes, the nozzle 58a may not be advanced, but the blower device 32 of the hot air unit 30 may be operated to open the common lid 82.

FIG. 14 is an explanatory view similar to FIG. 5, showing the outlet of a sanitary washing device according to a third modified example of the present invention.
In the above embodiment, the case where the entire outlet 13c is blocked by the nozzle lid 13d has been described as an example. However, the present invention is not limited to this. For example, as in a third modified example shown in Fig. 14, the outlet 90 may have a portion that is not blocked by the nozzle lid 13d even when the nozzle lid 13d is in a closed state.

As shown in FIG. 14, the front end of the bottom surface 13b may be spaced rearward from the lower end of the nozzle lid 13d. That is, the outlet 90 of the nozzle 58a has a front outlet 90a that opens forward and a lower outlet 90b that opens downward. The front outlet 90a and the lower outlet 90b are connected. The casing 12 has a nozzle lid 13d that covers the front outlet 90a in an openable and closable manner. That is, the nozzle lid 13d covers a portion of the outlet 90 (the front outlet 90a) in an openable and closable manner.

In such a case, the functional gas S may be released from the functional gas generator 37 without opening the nozzle lid 13d. The airflow Fs containing the functional gas S is guided to the lower discharge port 90b of the outlet 90 and discharged from the lower discharge port 90b toward the inside of the toilet 100 (bowl portion 101) without opening the nozzle lid 13d. As a result, mold, bacteria, and viruses in the nozzle storage portion 13 and the nozzle 58a can be efficiently suppressed.

In such a configuration, the first mode may be executed without opening the nozzle lid 13d. That is, the first angle of the nozzle lid 13d in the first mode is 0 degrees or more. The airflow Fs is guided to the lower exhaust port 90b, for example, even if the opening angle (first angle) of the nozzle lid 13d is 0 degrees. This makes it possible to save power, for example, since there is no need to extend the nozzle 58a. Also, since the nozzle lid 13d does not open, the first mode can be executed without the user noticing. The second and third modes may be executed, for example, by setting the opening angle of the nozzle lid 13d to 0 degrees or more.

In the above embodiment, the nozzle lid 13d is provided at the outlet 13c of the nozzle 58a. However, the present invention is not limited to this, and for example, the nozzle lid 13d does not have to be provided. In such a case, the first to third modes can be executed by changing the output of the blower 39.

In the above embodiment, the nozzle lid 13d is opened in the first to third modes. However, the present invention is not limited to this, and for example, the nozzle lid 13d does not have to be actively opened in the first to third modes. In such a case, the first to third modes can be executed by changing the output of the blower 39. In this case, the nozzle lid 13d is opened by the airflow Fs from the blower 39. In addition, in the first to third modes, only the output of the blower 39 may be changed without changing the open angle of the nozzle lid 13d.

In the above embodiment, the functional gas generator 37 is provided downstream of the blower 39 in the flow direction of the airflow F. However, the present invention is not limited to this embodiment, and the functional gas generator 37 may be provided upstream of the blower 39, for example, as long as it is possible to generate an airflow Fs directed toward the outlet 13c.

In the above embodiment, an example was described in which the airflow Fs was generated from the rear side of the nozzle 58a toward the outlet 13c. However, the present invention is not limited to this, and the airflow Fs may be generated, for example, from the side of the nozzle 58a (nozzle storage section). In other words, the airflow Fs may come into contact with at least a portion of the nozzle 58a and flow toward the outlet 13c.

In the above-described embodiment, the airflow Fs is discharged only from the outlet 13c. However, the present invention is not limited to this embodiment, and the airflow Fs may be discharged from another outlet in addition to the outlet 13c. For example, another outlet that communicates with the toilet room TR may be provided on the outer surface of the casing 12, and part of the airflow Fs may be discharged from this other outlet. Also, for example, another outlet that communicates with the bowl portion 101 may be provided on the outer surface of the casing 12, and part of the airflow Fs may be discharged from this other outlet.

In the above embodiment, an example was described in which one nozzle 58a is provided. However, the present invention is not limited to this, and may have, for example, multiple nozzles. For example, a nozzle for buttocks and a nozzle for bidet may be aligned in the left-right direction.
