Description

  The present invention relates to a sanitary washing device for washing a local part of a human body with washing water such as warm water, and in particular, a drying mechanism for drying the surface of a wet local part or the like after washing by blowing air and blowing hot air. The present invention relates to a sanitary washing device provided with

  In the technical field of a sanitary washing apparatus for washing a local part or the like of a human body, it has been proposed to provide various functions in order to realize washing according to the user's preference. If it is the sanitary washing apparatus which has such a function, the user can perform a comfortable local washing | cleaning. However, after cleaning the local area, the user removed water droplets adhering to the local area using sanitary paper such as toilet paper. In recent years, therefore, it has been proposed to provide a sanitary washing apparatus with a drying function in order to remove water droplets adhering to a local area without using sanitary paper.

  For example, in Patent Document 1, in addition to a drying mechanism that blows out hot air, an air injection unit that scatters or diffuses water droplets (residual adhering water droplets) adhering to a user's site to be cleaned (such as a local portion) is provided. Sanitary washing devices have been proposed. 18 is a top view of the sanitary washing device disclosed in Patent Document 1, and FIG. 19 is a partial cross-sectional view of the sanitary washing device.

  As shown in FIGS. 18 and 19, the sanitary washing device disclosed in Patent Document 1 includes a toilet seat 502 disposed on a toilet 501, a toilet lid 503, a body case 504 of the sanitary washing device, and a water washing tank (low tank). 509. The main body case 504 includes a hot air blowing device 505, a washing water injection nozzle 508, a washing water pumping pump 511, a hot water tank 512, an air compressor 513, a high-pressure air reservoir 514, and a solenoid valve 515. The hot air blowing device 505 has an air path 506 and a hot air blowing port 507, and is configured to blow hot air to a local area. The washing water spray nozzle 508 sprays hot water locally. The cleaning water supply pump 511 and the hot water tank 512 supply hot water to the cleaning water injection nozzle 508. The air compressor 513 compresses air, and the high-pressure air reservoir 514 stores compressed high-pressure air. The electromagnetic valve 515 is connected to the high-pressure air reservoir 514 and also connected to the high-pressure hose 517.

  The toilet seat 502 is provided with a cavity 516 therein, and a plurality of air ejection nozzles 518 are provided at the inner edge of the toilet seat 502 so as to be connected to the cavity 516. The cavity 516 is connected to the electromagnetic valve 515 via the high pressure hose 517. When the solenoid valve 515 is opened, high-pressure air is sent from the high-pressure air reservoir 514 to the cavity 516 via the high-pressure hose 517, and high-pressure air is ejected from the air ejection nozzle 518 connected to the cavity 516. That is, in the sanitary washing apparatus having the above-described configuration, the air compressor 513, the high-pressure air reservoir 514, the electromagnetic valve 515, the high-pressure hose 517, the cavity 516 in the toilet seat 502, and the air ejection nozzle 518 constitute an air ejection means.

  When the human body 510 sits on the toilet seat 502 and performs the washing operation after the toilet, the washing water supply pump 511 operates, and hot water is jetted from the washing water jet nozzle 508 through the hot water tank 512 to the surface to be washed. The local part is washed by After cleaning, the air compressor 513 is operated by a drying operation, and high-pressure air is ejected in the vicinity of the local area through the high-pressure air reservoir 514, the electromagnetic valve 515, the high-pressure hose 517, the cavity 516, and the air ejection nozzle 518, and water droplets adhered to the local area. Blow away to spread or diffuse. Next, the hot air blowing device 505 is operated, hot air is blown out from the hot air outlet 507 through the air passage 506, and the vicinity of the local area is dried.

  If the sanitary washing device has only a drying mechanism, it takes several minutes to dry the local area by blowing hot air. Therefore, when the hot air temperature is increased and the air volume is increased in order to shorten the drying time, there is a problem that the thermal feeling for the user is too strong and not suitable for practical use. In the sanitary washing device disclosed in Patent Document 1, it is intended to drastically shorten the drying time by including the air injection means as described above.

JP-A-58-218531

  However, the conventional sanitary washing apparatus having the air injection means has a problem that the user feels cold due to the injection of pressurized air, and there is room for improvement.

  For example, in the sanitary washing device disclosed in Patent Document 1, once air is stored in the high-pressure air reservoir 514 from the air compressor 513, the air heated during pressurization is cooled by heat dissipation from the high-pressure air reservoir 514. . For this reason, when the high-pressure air is released from the air ejection nozzle 518, heat may be taken away due to the expansion of the air, and the user may be extremely cold. Furthermore, since the water droplets adhering to the local part of the human body evaporate, the amount of heat corresponding to the heat of vaporization (latent heat) of water is deprived from the human body, so that it feels colder.

  The present invention has been made in view of the above-described problems of the prior art, and in a sanitary washing apparatus provided with a drying mechanism for drying a local part after washing, the user is given excessive coldness and heat. An object of the present invention is to provide a sanitary cleaning device that can efficiently dry a surface to be cleaned in a short time.

In order to solve the above-described problems of the prior art, the present invention provides:
A toilet seat having a seating surface;
A washing water jetting part for jetting washing water to a local part of a user seated on the toilet seat part;
An air injection unit having a cylindrical nozzle having an air outlet at the tip thereof for injecting pressurized air to the local part of the user and its surroundings after the washing water is ejected by the washing water ejection part;
A nozzle support that supports the nozzle so as to be able to advance and retreat in the direction of the axis;
An advancing / retreating drive means fixed to the nozzle support and driving the nozzle to advance / retreat in the axial direction;
A hot air generating unit that generates hot air, a tip portion having a hot air blowing port that blows the hot air toward a user's local area, and a temperature for supplying hot air generated from the hot air generating unit to the tip portion A wind supply pipe, a hot air drying section having,
The hot air drying unit generates the hot air, and starts the blowing of the hot air simultaneously with the start of the jet of air by the air jet unit or before the start of the jet of air, and the hot air drying unit and the hot air drying unit A control unit for controlling at least the unit;
Have
The leading end of the warm air drying section has a traveling direction of the warm air from the warm air blowing port substantially parallel to the direction of the axis of the nozzle, and a traveling direction of the pressurized air ejected from the air ejection port. Arranged along the side of the nozzle to cross,
A sanitary washing device is provided (claim 1).

With the above configuration, the warm air generated from the warm air blowing port formed at the tip of the warm air drying unit travels along the side surface of the nozzle, and flows into the pressurized air ejected from the air ejection port. It will merge and change its direction of travel, and will go to the user's local area with pressurized air.

  Therefore, compared with the conventional sanitary washing apparatus described above, hot air efficiently hits the user's local area in addition to the pressurized air. Thereby, according to the sanitary washing apparatus of this invention, it becomes possible to dry a to-be-cleaned surface efficiently in a short time, without giving excessive coldness and heat with respect to a user.

  In addition, the sanitary washing device of the present invention can reduce the air volume by narrowing the range of blowing hot air compared to the conventional one, so the hot air generating unit is reduced in size and weight (small and lightweight such as hot air fan) ), The amount of heat in the hot air generator can be reduced (the amount of heat in the heater etc. can be reduced).

Here, in the present invention, the range of the “surface to be cleaned” is preferably a range that can be contaminated by the excretion of the user in the human body local area and the vicinity thereof. This “surface to be cleaned” is a range of experiments and simulations taking into account the user's body shape distribution, toilet bowl size, toilet bowl shape, wash water discharge volume range, wash water discharge pressure range, etc. You may obtain | require and set beforehand by either of these. In addition, the range of this “surface to be cleaned” is determined every time the user uses the sanitary cleaning device by a sensor that can detect the range that can be soiled by excretion (such as an infrared sensor that detects moisture in the excrement). Alternatively, the optimum range may be obtained by sensing.

  Here, in the present invention, the range of the “surface to be dried” is preferably a range that can be wetted with the cleaning water when it is cleaned with the cleaning water in and around the human body part. Furthermore, the range (area) of the “surface to be dried” is equal to or greater than the range (area) of the “surface to be cleaned”, and the “surface to be dried” is set to include the entire range of the surface to be cleaned. Is preferred. In addition, this “range that can be wetted with cleaning water” usually includes the above-mentioned “surface to be cleaned”, that is, “the range that can be contaminated by the excretion of the user in and around the human body part” If the “surface to be cleaned” does not include the “surface to be cleaned” range, the range of “surface to be dried” is the range of “surface to be wet with cleaning water” and “surface to be cleaned”. It is preferable that it is the range containing.

  This “surface to be dried” range is based on experiments and simulations, taking into account the user's system distribution, toilet size, toilet shape, pressurized air discharge volume range, pressurized air discharge pressure range, etc. You may obtain | require and set beforehand by either of these. In addition, the range of this “surface to be dried” is sensed every time the user uses the sanitary cleaning device by a sensor that can detect the range that can be wetted by cleaning water (such as an infrared sensor that detects moisture). It is good also as a structure which calculates | requires the optimal range.

  Further, from the viewpoint of obtaining the above-described effects of the present invention more reliably, in the sanitary washing device of the present invention, the nozzle support section has a nozzle guide section having a through hole having an inner diameter through which the nozzle can pass. A part of the downstream part of the hot air supply pipe of the hot air drying part is connected to the nozzle guide part, and the tip part of the hot air drying part is formed in the nozzle guide part. Is preferably formed in the vicinity of the through hole of the nozzle guide portion (claim 2).

  The above object, other objects, features, and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments with reference to the accompanying drawings.

In addition, the toilet lid automatic opening / closing switch 231a, the toilet seat automatic opening / closing switch 231b, the warm air temperature adjustment switch 240, the water temperature adjustment switch 232, the toilet seat temperature adjustment switch 233, the power saving switch 234, the sterilization switch 235, and the toilet bowl washing switch 236 are provided. Is provided. On the left side of each figure of the hot air temperature adjustment switch 240, the water temperature adjustment switch 232, and the toilet seat temperature adjustment switch 233, a temperature hand bell that indicates the levels of the hot air temperature, the water temperature, and the toilet seat temperature in stages. Display units 239, 237, and 238 are provided.

  Each of the switches is configured as a button switch except for the toilet lid automatic opening / closing switch 231a, the toilet seat automatic opening / closing switch 231b, and the toilet seat washing switch 236. The toilet lid automatic opening / closing switch 231a, the toilet seat automatic opening / closing switch 231b, and the toilet seat washing switch 236 are configured as a knob changeover switch. If each switch is a button switch, the user operates the switch by pressing the front of the button. If the switch is a knob switch, the user switches the knob to the “OFF” or “ON” position. To operate the switch.

  When the user operates each of the switches, as shown in FIG. 2, a predetermined signal corresponding to the operation content of each switch is transmitted from the remote operation unit 120 to the main body unit 110. In main body 110, control unit 60A controls the operation of main body 110 based on the received signal. Although not shown in FIG. 2, if the toilet seat 130 and the toilet lid 140 are configured to be opened and closed by an automatic opening / closing mechanism, a signal from the remote control unit 120 or the entrance sensor 102 is transmitted from the main body 110. By receiving, the toilet lid part 140, or the toilet lid part 140 and the toilet seat part 130 may be configured to automatically open and close under the control of the control part 60A.

  The operation of each switch and the corresponding sanitary washing apparatus 101 will be described. For example, when the user operates the buttocks switch 212 or the bidet switch 213, cleaning water is jetted from the shared nozzle unit 20 described later to the surface to be cleaned of the user. Further, when the user operates the stop switch 211, the ejection of cleaning water from the shared nozzle unit 20 to the surface to be cleaned of the user is stopped.

  Further, when the user operates the drying switch 214, air is blown from the air jet unit 50, which will be described later, to the surface to be dried of the user, and at the same time, hot air is blown from the hot air drying unit 40. In addition, since the user selects and operates the drying mode switches 220a, 220b, and 220c, the air ejection conditions and the hot air blowing conditions that are ejected to the surface to be dried of the user are changed. Any one of the drying modes can be arbitrarily selected according to the usage status of the apparatus 101 and the user's preference. For example, in the present embodiment, by operating the drying mode switch 220a, the “rapid drying operation” when drying is desired to be completed in a short time, and by operating the drying mode switch 220b, the local portion is reliably dried. By operating the drying mode switch 220c, the “warm air drying operation” for blowing out only the warm air when it is not desired to apply air can be selected.

  In addition, the user can adjust the flow rate, pressure, and the like of the cleaning water ejected to the user's local area by operating the strength adjustment switches 222 and 223. Furthermore, the user can adjust the position of the tip of the shared nozzle unit 20 by operating the position adjustment switches 225 and 226. Thereby, the ejection position of the washing water with respect to the user's local part can be adjusted. Even when these switches are operated, a predetermined signal corresponding to each switch is wirelessly transmitted from the remote operation device 120 to the main body 110. Thereby, the control unit 60A of the main body 110 controls the operation of the main body 110 based on the received signal.

  The user can set the opening / closing operation of the toilet lid 140 by operating the knob of the toilet lid automatic opening / closing switch 231a. That is, when the knob of the toilet lid automatic opening / closing switch 231a is in the on position, the toilet lid 140 is automatically opened and closed according to the user entering the toilet room. The same applies to the toilet seat automatic opening / closing switch 231b. Further, the user can adjust the temperature of the hot air blown from the hot air drying unit 40 to the user's local area by operating the hot air temperature adjustment switch 240. Each time the hot air temperature adjustment switch 240 is pressed, the setting is switched between “high”, “medium”, “low”, and “off”. When operating with this “off” setting, the hot air generating unit 44 provided in the hot air drying unit 40 is turned off and only air is blown. Further, the user can adjust the temperature of the cleaning water ejected from the shared nozzle portion 20 to the user's local area by operating the water temperature adjustment switch 232. The user can adjust the heating temperature of the toilet seat in the toilet seat 130 by operating the toilet seat temperature adjustment switch 233.

Note that a hot air temperature automatic mode, which is a function for automatically adjusting the air temperature according to a detection value of a room temperature detection unit (described later) provided in the main body 120, is provided, and a switch for executing it is separately received. May be. Thus, a comfortable air blowing temperature can be automatically obtained regardless of the season or the room temperature without the troublesome operation of the hot air temperature adjustment switch 240 by the user.

  Next, the washing water ejection unit 30, the hot air drying unit 40, the air injection unit 50, the detection sensor unit 70, and the control unit 60A included in the main body unit 110 will be specifically described.

[Washing water ejection part]
As shown in FIG. 4, the washing water ejection unit 30 includes a hot water heating unit 31, a switching valve 32, a common nozzle unit 20 as a washing nozzle unit, an on-off valve 34, and a nozzle moving mechanism 52. The washing water ejection unit 30 is connected to a water pipe (not shown) and the washing water pipe 26. The cleaning water pipe 26 is connected to an on-off valve 34, and tap water as cleaning water is supplied to or shut off from the common nozzle unit 20 by opening / closing the on-off valve 34. In FIG. 4, the supply of tap water is indicated by an arrow W0, and tap water as washing water flows in the direction of this arrow W0.

  A hot water heating unit 31 is connected to the downstream side of the flow of cleaning water in the on-off valve 34 via a cleaning water pipe 26. The hot water heating unit 31 is a heater that heats the cleaning water (tap water) flowing through the cleaning water pipe 26. For example, the warm water heating unit 31 is in contact with the serpentine heating water channel through which the cleaning water flows and the entire heating water channel. A configuration in which the flat ceramic heater to be arranged is provided in the case can be given. If it is this structure, it is not necessary to provide the warm water tank which hold | maintains washing water at predetermined temperature, and when washing | cleaning is required, washing water can be warmed to predetermined temperature instantaneously. Of course, the warm water heating unit 31 may be configured to include a warm water tank.

  A switching valve 32 is connected to the downstream side of the flow of washing water in the hot water heating unit 31 as indicated by a broken line in FIG. As shown by a broken line in FIG. 1, the switching nozzle 32 is connected to the common nozzle portion 20 via the washing water pipe 26 and the toilet bowl (not shown) via the drain pipe 27. 103 is also connected to the inside. Then, by switching the switching valve 32, the wash water (warm water) warmed to a predetermined temperature supplied from the hot water heating unit 31 is supplied to the common nozzle unit 20 or to the inside of the toilet 103. It is drained (indicated by arrow W2 in FIG. 4).

  The common nozzle unit 20 is a cleaning nozzle unit that cleans a user's local part (surface to be cleaned) seated on the toilet seat unit 130 with warm water, and is housed in the main body unit 110 when not in use. During use, the nozzle moves from the main body 110 by the nozzle moving mechanism 52 and, as shown by an arrow W1 in FIG. Further, as will be described later, the common nozzle unit 20 is integrated with an air nozzle unit (not shown) in the air injection unit 50. The nozzle moving mechanism 52 includes a first drive motor 53 and a second drive motor 54 (indicated by M1 and M2 in the figure, respectively), and moves the shared nozzle unit 20 to thereby move the shared nozzle unit with respect to the user's local area. The position of the washing water jet port 22 on the front end side of 20 is relatively moved. Furthermore, the common nozzle part 20 is integrated with a hot air supply port (not shown) and a hot air supply pipe (not shown) in the hot air drying part 40.

  The common nozzle unit 20 and the nozzle moving mechanism 52 will be described in detail after the hot air drying unit 40 and the air injection unit 50 are described.

The controller 60A controls the opening / closing of the opening / closing valve 34, the heating of the washing water by the hot water heating unit 31, the switching of the switching valve 32, and the operation of the nozzle moving mechanism 52 for moving the common nozzle unit 20. Although not shown in FIG. 4, the hot water heating unit 31 and the nozzle moving mechanism 52 include a drive unit that operates them, and the control unit 60A outputs a control signal to these drive units, whereby the hot water heating unit 31 and The operation of the nozzle moving mechanism 52 is controlled. The on-off valve 34 and the switching valve 32 are also provided with a drive unit, and the control unit 60A controls the opening / closing of the on-off valve 34 and the switching of the switching valve 32 by outputting a control signal to these driving units.

[Hot air drying section]
As shown in FIG. 5, the hot air drying unit 40 includes an air fan 41, a tip 48, a hot air supply pipe 43, and a hot air generation unit 44. In FIG. 5, the air fan 41 and the hot air generator 44 are illustrated as a configuration in which each is connected by a double line in this order, but as shown by a broken line in FIG. The wind generating unit 44 is integrated by connecting the air fan 41 and the hot air generating unit 44.

  The distal end portion 48 is configured with a warm air blowing port 42 that blows warm air toward the user's local area, and the warm air supply for supplying the distal end portion 48 with the warm air generated by the warm air generating portion 44. The tube 43 is connected.

  The air fan 41 is composed of, for example, a multi-blade fan, and takes its outside air and forms an air flow by its own rotation, as schematically shown by an arrow A0 in FIG. The hot air generator 44 is provided, for example, near the air outlet of the air fan 41 and heats the air flow to a predetermined temperature. Thus, warm air is generated and guided to the tip 48 by the warm air supply pipe 43, and warm air is blown from the warm air blowing port 42 as shown by an arrow A2 in FIG. Air is ejected from the common nozzle part 20 from an air jet part 50 described later. In addition, the air fan 41 and the hot air generating unit 44 are controlled by the control unit 60A so as to start blowing warm air from the hot air blowing port 42 at the same time as the start of air ejection or before the start of air ejection. ing.

  The tip 48 of the hot air drying unit 40 has air traveling in the direction in which the warm air exiting from the hot air blowing port 42 is substantially parallel to the axial direction of the common nozzle unit 20 and is ejected from the air ejection port 21. Is arranged along the side surface of the common nozzle part 20 so as to cross the traveling direction (arrow A1 in FIG. 5), and the temperature generated from the hot air blowing port 42 formed at the tip 48 of the hot air drying part 40. The wind travels along the side surface of the nozzle, and merges with (flows of) air ejected from an air ejection port 21 of the air ejecting section 50 to be described later and changes its traveling direction. Will head.

  Therefore, hot air efficiently hits the user's local area in addition to air, and the surface to be cleaned can be efficiently and quickly applied to the user without giving excessive coldness and heat to the user. It becomes possible to dry.

  In addition, because hot air is efficiently applied pinpointly, the air flow can be reduced by narrowing the range of hot air, so the hot air generator is smaller and lighter (smaller and lighter for hot air fans, etc.) Further, it is possible to reduce the amount of heat of the hot air generator (reduction of the amount of heat of the heater, etc.).

  In addition, the wind speed of the warm air blown from the warm air blowing port 42 is slower than the wind speed of the air ejected from the air ejecting unit 50 described later, and is, for example, 10 m or less per second in the present embodiment.

[Air injection part]
As shown in FIG. 5, the air injection unit 50 includes an air pump 51, a nozzle moving mechanism 52, and a common nozzle unit 20. The air pump 51 and the common nozzle part 20 are connected by an air pipe 25 as indicated by a broken line in FIG. As schematically shown by an arrow A0 in FIG. 5, the air pump 51 generates air by taking in outside air and pressurizing it, and sends the air to the common nozzle unit 20 via the air pipe 25. The common nozzle portion 20 is an air nozzle portion that injects air, and an air injection port 21 is formed on the tip side of the common nozzle portion 20 separately from the cleaning water jet port 22. In FIG. 5, air is injected as indicated by an arrow A1. As described above, the nozzle moving mechanism 52 moves the position of the air injection port 21 on the distal end side of the shared nozzle part 20 relative to the local part of the user by moving the shared nozzle part 20.

  The wind speed of the air ejected from the air ejection port 21 of the common nozzle part 20 is set to be within a range of, for example, 20 to 30 m per second when reaching the local part, and the temperature of the warm air drying part 40 described above is set. It is larger than the wind speed of the warm air blown from the wind blowing port 42.

  The hot air blown from the hot air blowing port 42 of the hot air drying unit 40 is an air flow for drying the local part and its surroundings, but the air injected by the air injection unit 50 is the local part and its air. It is an air flow for removing water droplets adhering to the surroundings (surface to be dried). Therefore, the air ejected from the air ejection port 21 needs to be concentrated and ejected in a spot shape rather than being blown so as to spread over the entire local area like the warm air. For example, in this embodiment, various conditions are set so that the air ejected from the air ejection port 21 has a diameter of about 1 cm when reaching the surface to be dried.

  The warm air blown from the warm air blowing port 42 of the warm air drying unit 40 merges with the air (flow) ejected from the air ejection port 21 and changes its traveling direction, and goes to the user's local area together with the air. It will be. At that time, it is attracted by the flow of air and heads to the local area of the user.

  The operation of the air fan 41, the operation of the air pump 51, the operation of the hot air generation unit 44, and the operation of the nozzle moving mechanism 52 that moves the common nozzle unit 20 are controlled by the control unit 60A. Although not shown in FIG. 5, the air fan 41, the air pump 51, and the hot air generation unit 44 include a drive unit that operates them, and the control unit 60 </ b> A outputs a control signal to these drive units, whereby the air fan 41, the operation of the air pump 51, the warm air generator 44, and the nozzle moving mechanism 52 is controlled.

  As described above, in the present embodiment, the wind speed (flow velocity) of air is in the range of 20 to 30 m / s. However, in order to obtain the effect of blowing water droplets, the wind speed is generally 10 m / s or more. preferable. The size of the range in which the air jet contacts the surface to be dried depends on the size and number of the air jets 21, but the size and number of the air jets 21 are not particularly limited. What is necessary is just to set in consideration of the capacity and the wind speed of air.

[Detection sensor]
In this embodiment, the detection sensor unit 70 includes a seating sensor 71 shown in FIG. 1 and a room temperature detection unit 72 shown in FIG. As shown in FIG. 1, the seating sensor 71 is provided on the upper front portion of the main body 110 and detects that a user is seated on the toilet seat 130. The specific configuration of the seating sensor 71 is not particularly limited, but in the present embodiment, for example, a reflective infrared sensor is used. If the seating sensor 71 is an infrared sensor, it detects that the user is seated on the toilet seat 130 by detecting infrared light reflected from the human body.

  The room temperature detection unit 72 detects the room temperature of the toilet room in which the sanitary washing device 101 is installed. In the present embodiment, as described later, the detected room temperature is controlled by the control unit 60A for air temperature correction. Used for. Although the specific structure of the room temperature detection part 72 is not specifically limited, In this embodiment, it is a thermistor built in the main-body part 110. FIG.

In this embodiment, as the detection sensor unit 70, in addition to the seating sensor 71 and the room temperature detection unit 72, a nozzle that is provided in a nozzle moving mechanism 52 described later and detects the position of the common nozzle unit 20 in the left-right direction. A position sensor and a hot water heater 31 are provided, and a flow rate sensor (not shown in FIG. 4) and a hot water temperature sensor (not shown) provided in the hot water heater 31 are included. The detection sensor unit 70 is not limited to these, and other known sensors and detection devices may be used. In the present embodiment, since the room temperature (atmosphere temperature at the time of drying) is used as the control information of the blast temperature correction control by the control unit 60A, the room temperature detection unit 72 is provided, but depending on the type of control by the control unit 60A The detection sensor unit 70 may not be provided.

[Common nozzle part]
As shown in FIG. 6, the common nozzle portion 20 has a cylindrical nozzle body 20 a, and an air injection port 21 and a cleaning water injection port 22 are formed on the outer peripheral surface on the tip side. In the present embodiment, the air injection port 21 is formed on the distal end side of the nozzle body 20 a with respect to the washing water injection port 22. Inside the nozzle body 20a, an air cavity 23 and a cleaning water cavity 24 extending along the longitudinal direction of the nozzle body 20a are formed. One end of the air cavity portion 23 is connected to the air injection port 21 on the front end side of the nozzle body 20a, and the other end portion is exposed on the bottom surface on the rear end side of the nozzle body 20a. 25. The cleaning water cavity 24 also has one end connected to the cleaning water jet port 22 on the front end side, the other end exposed on the bottom surface on the rear end side, and is connected to the cleaning water pipe 26 at this site. Yes.

  Accordingly, the hot water heated by the hot water heating unit 31 of the cleaning water ejection unit 30 is supplied to the cleaning water cavity 24 from the rear end side of the nozzle body 20a via the cleaning water pipe 26, and the cleaning water jet port on the front end side is supplied. 22 is ejected. The air pressurized by the air pump 51 of the air injection unit 50 is supplied to the air cavity 23 from the rear end side of the nozzle body 20a via the air pipe 25 and is injected from the air injection port 21 on the front end side. .

  The specific shape, dimensions, material, and the like of the nozzle body 20a are not particularly limited, and a known configuration can be suitably used in the fields of a sanitary washing device and a toilet device. For example, in FIG. 6, the mode in which the air injection port 21 is formed on the distal end side of the nozzle body 20 a with respect to the cleaning water injection port 22 has been described, but in the present invention, the air injection port 21 and the cleaning in the nozzle body 20 a are cleaned. The positional relationship with the water outlet 22 is not particularly limited. For example, in the present invention, the washing water jet port 22 may be formed on the tip side of the nozzle body 20 a with respect to the air jet port 21. Further, for example, the washing water jet port 22 and the air jet port 21 are arranged on the tip side of the nozzle body 20a at the same position in the axial direction of the nozzle body 20a so as to be aligned perpendicular to the axial direction. It may be.

  The air pipe 25 and the washing water pipe 26 may be made of a material that can withstand the air pressure and the washing water pressure, but at least in the vicinity of the portion connected to the nozzle body 20a, a rubber material or the like is used. It is preferable to be formed of a material having such flexibility. This is because the nozzle body 20a moves forward and backward or swings by the nozzle moving mechanism 52, so that the air pipe 25 and the washing water pipe 26 connected to the rear end side of the nozzle body 20a are twisted or bent. This is because a large external force is applied.

Moreover, although the air injection port 21 and the washing water jet port 22 which are formed in the common nozzle part 20 are each one as shown in FIG. 6, it is not limited to this, Even if it forms multiple, respectively Good. For example, a cleaning water jet for “wet cleaning” and a cleaning water jet for “bidet cleaning” may be formed independently on the nozzle body 20a. In addition, if it is the structure which injects air only from the single air injection port 21, even if the flow volume of air is small, since the flow velocity can be enlarged, the air pump 51 with which the air injection part 50 is provided has a small capacity | capacitance. Even if there is, sufficient air can be injected. That is, since the jet of air is large, when air hits a water droplet attached to the surface to be dried, the energy for peeling the water droplet from the skin surface can be increased. Therefore, it becomes possible to blow off water drops efficiently.

  In the present embodiment, as described above, the common nozzle unit 20 has a configuration in which the cleaning nozzle unit in the cleaning water ejection unit 30 and the air nozzle unit in the air injection unit 50 are integrated. Without being limited to the configuration, the cleaning nozzle part in the cleaning water ejection part 30 and the air nozzle part in the air injection part 50 may be provided independently in the main body part 110. Alternatively, the cleaning nozzle unit may have a configuration in which a “wet cleaning” nozzle and a “bide cleaning” nozzle are provided instead of a single nozzle. Of course, as in the present embodiment, since the integrated common nozzle portion 20 is provided, the installation area of the nozzle can be reduced and the nozzle moving mechanism 52 is also shared. The number of members can be reduced and the main body 110 can be reduced in size and cost. Alternatively, the air nozzle unit may include a plurality of nozzles. With such a configuration, since a plurality of air jets can be formed, water droplets on the surface to be dried can be easily collected at the center of the surface to be dried, as will be described later, and the drying time can be further shortened.

[Nozzle part peripheral arrangement and moving mechanism]
As shown in FIG. 6, the nozzle moving mechanism 52 includes a first drive motor 53, a second drive motor 54, a nozzle support portion 55, and a nozzle movement portion 57 in the present embodiment.

  In the present embodiment, the nozzle support portion 55 has a substantially right triangular plate-like outer shape and has a thickness that is equal to or greater than the diameter of the nozzle body 20a. The surface corresponding to the bottom side of the right triangle is the bottom surface of the nozzle support portion 55, and the surface corresponding to the oblique side of the right triangle is a placement surface 56c on which the nozzle body 20a is movably placed. The mounting surface 56c is inclined so that the rear side is high and the front side is low, and a pair of rail portions 56a and 56a are provided along the longitudinal direction thereof. In addition, a nozzle guide portion 56b protruding upward is formed on the front side of the placement surface 56c. The nozzle guide portion 56b is formed with a through-hole 56d having an inner diameter through which the nozzle body 20a can pass, so that the nozzle body 20a does not come off the placement surface 56c when moving forward and backward on the placement surface 56c. The nozzle body 20a is supported.

  A part of the downstream portion of the hot air supply pipe 43 in the hot air drying unit 40 is connected to the nozzle guide portion 56b, and a tip 48 in the hot air drying unit 40 is formed in the nozzle guide portion 56b. A warm air blowing port 42 is formed at the distal end portion 48 of the nozzle body 20 a where the air injection port 21 and the washing water ejection port 22 are provided.

  In addition, since the warm air heated by the warm air generation part 44 passes, it is preferable that the warm air supply pipe | tube 43 is formed with the material which has the pressure resistance and heat resistance with respect to a warm air.

  Further, in the present embodiment, as described above, the hot air supply pipe 43 is configured in consideration of pressure resistance and heat resistance. However, the configuration is not limited to such a configuration, and the hot air supply pipe 43 has a substantially cross-sectional shape. You may form with the material which has circular shape and flexibility.

  With this configuration, it is possible to maintain a uniform circular cross-section from the hot air generator 44 to the tip 48, the cross-sectional shape of the hot air supply pipe 43 to which the hot air is blown is deformed from a substantially circular shape, and It is possible to prevent the flow rate of the hot air from being lowered due to the sudden expansion of the air blowing path.

The hot air supply pipe 43 may be formed in a bellows shape. With this configuration, stretchability by the bellows-like portion that is folded in a narrow shape is obtained, and more flexible flexibility is obtained. Therefore, it is possible to sufficiently prevent the flow path from being bent by the sudden bending of the flow path, and the cross-sectional shape of the flow path from being deformed from a substantially circular shape. Increase in loss can be sufficiently prevented.

  Further, since the hot air supply pipe 43 has a bellows shape, the degree of freedom of component placement is improved in the sanitary washing device.

  In the present embodiment, as shown in FIG. 6, the nozzle guide portion 56 b is integrally provided with the hot air supply pipe 43, the tip portion 48, and the hot air blowing port 42, but this is not limitative. Not.

  Since the hot air blowing port 42 is formed in the vicinity of the through hole 56d of the nozzle guide portion 56b, it is formed integrally with the nozzle guide portion 56b, so that the number of parts is not increased and the cost can be reduced. I can do it. Moreover, since the guide component molded integrally is formed of a known resin material, it is possible to avoid an increase in cost due to a special material.

  Both the rail part 56a and the nozzle guide part 56b should just be formed with the well-known resin material. Here, in the nozzle guide portion 56b, not only the nozzle body 20a moves back and forth inside the through hole 56d, but also when the shared nozzle portion 20 swings, the nozzle body 20a rotates inside the through hole 56d. Therefore, at least a portion that becomes the inner peripheral surface of the through hole 56d in the nozzle guide portion 56b is formed of a material having a good sliding property so that the nozzle body 20a can easily move back and forth or rotate within the through hole 56d. It is preferable. Further, the diameter of the through hole is such that an appropriate gap is obtained between the outer peripheral surface of the nozzle main body 20a and the inner peripheral surface of the through hole 56d in a state where the nozzle main body 20a has penetrated. Is preferred.

  The length of the mounting surface 56c of the nozzle support portion 55 is equal to or greater than the length of the nozzle body 20a. This is because the entire nozzle body 20 a is placed and supported on the placement surface 56 c of the nozzle support portion 55 when the common nozzle portion 20 is completely stored in the body portion 110. Moreover, it is preferable that the pair of rail portions 56a and 56a formed on the mounting surface 56c is also formed of a material having good slidability. As will be described later, the nozzle support slider 58 fixed to the nozzle main body 20a on the rear end side of the nozzle main body 20a is sandwiched between the rail portions 56a and 56a, and the mounting surface 56c is moved in the longitudinal direction. It is for sliding along. In the present embodiment, as shown in FIG. 6, the rail portions 56 a and 56 a and the nozzle guide portion 56 b are provided integrally with the main body of the nozzle support portion 55, but the present invention is not limited to this. .

  The nozzle moving part 57 has a nozzle support slider 58, a swinging gear part 57a, and a slider guide part 57b. As described above, the nozzle support slider 58 is configured to slide on the mounting surface 56c with the mounting surface 56c of the nozzle support portion 55 sandwiched between the rail portions 56a and 56a. .

  The nozzle support slider 58 penetrates the nozzle fixing portion 58a fixed to the rear end side of the nozzle body 20a, the gear support portion 58b that supports the second drive motor 54 and the swinging gear portion 57d, and the slider guide portion 57b. The guide penetration part 58c is comprised. The nozzle fixing portion 58a is formed in a rectangular parallelepiped shape so as to cover the outer periphery of the nozzle main body 20a on the rear end side of the nozzle main body 20a. By passing the nozzle main body 20a through the nozzle fixing portion 58a, the nozzle main body 20a Fixed. The lower portion of the nozzle fixing portion 58a is a rail fitting portion that is slidably sandwiched between the rail portions 56a and 56a (not shown in FIG. 6). Further, the nozzle body 20a is rotatable on the front side of the nozzle fixing portion 58a.

  The gear support portion 58b is a plate-like portion extending from the nozzle fixing portion 58a on the placement surface 56c toward the outside of the placement surface 56c, and the rocking gear portion 57a is supported on the front surface, and the rear surface on the rear surface. A second drive motor 54 is supported. Although not shown in FIG. 6, the rotation shaft of the second drive motor 54 passes through the gear support portion 58b and reaches the front surface, and the first end of the rotation shaft is included in the swing gear portion 57a. The gear is fixed. The guide penetration portion 58c is a plate-like portion extending downward from the end portion of the gear support portion 58b, and the slider guide portion 57b extending along the side of the placement surface 56c is penetrated.

  The slider guide portion 57b is a steel cord extending in one direction, and is provided on one side surface (front side surface in FIG. 6) of the nozzle support portion 55 so as to be inclined along the placement surface 56c. Yes. Both ends of the slider guide portion 57b are fixed by guide support plates 56e and 56f provided upright from the side surface of the nozzle support portion 55. Among these, the guide support plate 56e fixes the slider guide portion 57b on the rear side of the nozzle support portion 55, and the first drive motor 53 is supported on the rear surface thereof. The rotation shaft of the first drive motor 53 (not shown) passes through the guide support plate 56e and reaches the front surface. On the front surface, a shaft-like slider guide portion 57b is connected to the rotation shaft. That is, the slider guide portion 57b is configured to rotate when the rotation shaft of the first drive motor 53 rotates. The guide support plate 56f supports the end of the slider support portion 57b on the front side of the nozzle support portion 55 so that the slider guide portion 57b can rotate.

  A spiral screw is formed on the outer periphery of the slider guide portion 57b, and the through hole of the guide through portion 58c through which the slider guide portion 57b passes is a screw hole corresponding to this screw. That is, if the slider guide portion 57 b is a “bolt” that can be rotated by the first drive motor 53, the guide through portion 58 c of the nozzle support slider 58 corresponds to a “nut” corresponding to the bolt.

  The oscillating gear portion 57a is supported on the front surface of the gear support portion 58b. In the configuration shown in FIG. 6, the oscillating gear portion 57a includes a first gear, a second gear, and a third gear. As described above, the first gear is fixed to the rotation shaft of the second drive motor 54. A second gear is combined with the first gear, and a third gear is combined with the second gear. Since the third gear is fixed to the outer peripheral surface of the rear end of the nozzle body 20a, the nozzle body 20a is also rotated by the rotation of the third gear. Therefore, the nozzle body 20a is supported rotatably with respect to the nozzle support slider 58.

  The movement of the common nozzle unit 20 by the nozzle moving mechanism 52 having the above-described configuration will be described with reference to FIGS. 2, 4 and 5 in addition to FIG. When an operation command for performing local cleaning and drying using the common nozzle unit 20 is transmitted to the control unit 60A by the operation of the remote operation unit 120, the control unit 60A first turns the first drive motor 53 on. Rotate in the positive direction. Since the rotation shaft of the first drive motor 53 is connected to the slider guide portion 57b, the slider guide portion 57b also rotates in the forward direction.

  The slider guide portion 57b penetrates the guide penetration portion 58c of the nozzle support slider 58, and this penetration state is a fitting state of “bolts” and “nuts”. Therefore, the rotation of the slider guide portion 57b acts to advance the guide penetration portion 58c along the slider guide portion 57b. Since the guide penetrating portion 58c is a part of the nozzle support slider 58, an action of moving forward on the placement surface 56c is transmitted to the nozzle support slider 58, and therefore the nozzle support slider 58 moves forward of the placement surface 56c. Slide in the direction.

Here, the nozzle support slider 58 is connected to the common nozzle part 20 (via the nozzle fixing part 58a.
Since the nozzle body 20a is fixed to the rear end of the nozzle body 20a, the common nozzle portion 20 is applied with an external force that advances from the rear end side by the nozzle support slider 58. Therefore, the shared nozzle part 20 moves forward on the mounting surface 56 c of the nozzle support part 55, and its tip part is exposed to the outside of the main body part 110. At this time, the shared nozzle portion 20 is guided by the nozzle support slider 58 so that it does not come off between the rail portions 56a and 56a, and the front end side is guided by the nozzle guide portion 56b. The portion 20 moves forward without shifting on the placement surface 56c (in the direction of arrow D1 in FIG. 6).

  An air ejection port 21 and a washing water ejection port 22 are formed at the tip of the shared nozzle unit 20 exposed outside the main body 110. The hot air generator 44 is provided, for example, in the vicinity of the air outlet of the air fan 41, and heats the airflow to a predetermined temperature. Thus, warm air is generated and guided to the tip 48 by the warm air supply pipe 43, and warm air is blown from the warm air blowing port 42 as shown by an arrow A2 in FIG.

  FIG. 16 is a cross-sectional view of the shared nozzle portion 20 and the nozzle guide portion 56b shown in FIG.

  As shown in FIG. 16, the air nozzle 21 is provided in the nozzle guide portion 56 b of the common nozzle portion 20. The air generated by the air pump 51 passes through the air cavity 23 and is injected from an air injection port 21 (not shown).

  In addition, at the same time as the start of air ejection or before the start of air ejection, the warm air drying unit 40 is activated and warm air is blown through the warm air supply pipe 43. Thereafter, the hot air filled in the hot air blowing port 42 flows toward the tip where the air injection portion 21 of the nozzle 20 is located.

  The through hole 56d provided in the nozzle guide portion 56b moves between the through hole 56d and the nozzle 20 so that the nozzle body 20a can move back and forth on the mounting surface 56c. Clearance is provided in a range that does not cause backlash and other problems.

  The hot air blowing port 42 is provided so that the hole diameter is larger than the through hole 56d in order to blow the hot air toward the air injection port 21 of the common nozzle part 20. For this reason, the hot air blown from the hot air supply pipe 43 changes its direction at the hot air supply port 42 and is blown toward the air injection port 21 of the common nozzle unit 20.

  FIG. 17 is a side view of the common nozzle part 20 and the nozzle guide part 56b shown in FIG. 6 and shows the hot air flow. As shown in FIG. 17, the traveling direction of the warm air coming out of the warm air blowing port 42 (arrow A <b> 2 in the drawing) is substantially parallel to the axial direction of the common nozzle unit 20 and along the side surface of the common nozzle unit 20. And blown.

  Thereafter, the warm air blown from the warm air blowing port 42 intersects with the air ejection direction (arrow A1 in the figure) ejected from the air ejection port 21 and the ejection direction of the air ejected from the air ejection port 21 (FIG. It merges with the middle arrow A1), changes its traveling direction, and goes to the user's local area together with air.

Furthermore, as described above, the surface to be dried, which is a region where air and hot air are ejected, has a larger area than the surface to be cleaned. Therefore, the control unit 60A rotates the second drive motor 54 forward and backward in a predetermined pattern. Since the 1st gear which comprises rocking gear part 57a is being fixed to the rotating shaft of the 2nd drive motor 54, the rotational drive force of the 2nd drive motor 54 is via the 1st gear and the 2nd gear. , And transmitted to the third gear fixed to the rear end side of the common nozzle portion 20. As a result, the cylindrical common nozzle portion 20 rotates forward and backward (autorotates) in the axial direction thereof, so that the air outlet 21 at the tip end swings left and right (arrows in FIG. 6). D3 direction).

  Thereafter, when an operation command to end the cleaning and drying operations is transmitted from the remote operation unit 120 to the control unit 60A, the control unit 60A rotates the first drive motor 53 in the reverse direction. As a result, the slider guide portion 57b also rotates in the reverse direction, so that the nozzle support slider 58 moves backward on the placement surface 56c. Therefore, the common nozzle part 20 is retracted along the placement surface 56c of the nozzle support part 55 (in the direction of arrow D2 in FIG. 6), and as a result, the common nozzle part 20 enters the main body part 110 from the rear end side. It is pulled in and stored in the main body 110.

  That is, the first drive motor 53 is a drive source for moving the common nozzle portion 20 in the front-rear direction, and among the nozzle movement portions 57, the slider guide portion 57b and the guide penetration portion 58c of the nozzle support slider 58 are shared. It functions as a nozzle advance / retreat moving unit that moves the nozzle unit 20 back and forth. The second drive motor 54 is a drive source for moving the shared nozzle part 20 in the left-right direction. Of the nozzle moving part 57, the swinging gear part 57a swings the shared nozzle part 20 left and right. It functions as a nozzle swinging part.

  The nozzle moving mechanism 52 in the present embodiment includes the nozzle advancement / retraction movement unit, so that the common nozzle unit 20 protrudes from the main body unit 110 and is housed in the main body unit 110, and the front end portion of the common nozzle unit 20. Can be moved back and forth, and further, by providing the nozzle oscillating portion, the tip end portion of the common nozzle portion 20 can be moved left and right. Therefore, in particular, since the injection of air from the air injection port 21 can be moved not only forward and backward, but also to the left and right, it is possible to inject air over the user's local area and the entire periphery (the entire surface to be dried). it can.

  In the present embodiment, since the common nozzle unit 20 is composed of one nozzle, only one nozzle moving mechanism 52 is provided. However, when a plurality of nozzles are provided, the nozzle A plurality of moving mechanisms 52 may be provided in accordance therewith.

  In the present embodiment, the common nozzle unit 20 is configured to move the entire common nozzle unit 20 by the nozzle moving mechanism 52. However, the present invention is not limited to this. The structure which moves the contact | abutting range of air by moving only the surrounding members containing the exit 21 or changing an angle may be sufficient. Or the structure etc. in which the wind direction change part which changes the direction of the jet of air in front of an air nozzle part (not shown) may be provided.

[Control system for sanitary washing equipment]
As shown in FIGS. 2, 4 and 5, the control unit 60 </ b> A controls operations of the cleaning water ejection unit 30, the hot air drying unit 40, the air injection unit 50, and the like included in the sanitary washing device 101 according to the present embodiment. However, in the present embodiment, the control unit 60A includes a calculation unit 61, a storage unit 62, and a blower temperature correction unit 63 as shown in FIG.

  The calculation unit 61 uses the program stored in the storage unit 62 to perform calculation for controlling operations such as cleaning and drying in the sanitary washing apparatus 101. In addition to the program, the storage unit 62 stores various types of data used for calculation in the calculation unit 61. The calculation unit 61 and the storage unit 62 are constituted by, for example, a microcomputer CPU and an internal memory, respectively. Note that the storage unit 62 may be configured as an independent memory, and the storage unit 62 does not have to be a single unit, but as a plurality of storage devices (for example, an internal memory and an external hard disk drive). It may be configured.

The blower temperature correction unit 63 corrects the temperature of the warm air generated by the warm air drying unit 40 (blower temperature). More specifically, the blowing temperature correction unit 63 is a value that is initially set for the blowing temperature in the period (starting stage) from the start of blowing by the hot air drying unit 40 until the first predetermined time elapses. (Heating value) is corrected to a higher value (startup adjustment value). The calculation unit 61 acquires the corrected air temperature value from the air temperature correction unit 63, and controls the operation of the hot air drying unit 40 based on the corrected value. The air temperature correction unit 63 may be configured using a known temperature correction circuit, or a configuration realized by the calculation unit 61 operating according to a program stored in the storage unit 62, that is, the function of the control unit 60A. It may be a configuration.

  The operation unit 61 and the air temperature correction unit 63 are configured to receive various operation commands from the remote operation unit 120. The calculation unit 61 and the blowing temperature correction unit 63 are also configured to receive a detection value of the room temperature of the toilet room from the room temperature detection unit 72.

  In FIG. 7, the control system about the warm air drying part 40 and the air injection part 50 is illustrated (refer FIG. 5). Specifically, the calculation unit 61 controls the air fan driving unit 45, the hot air generating unit driving unit 46, the air pump driving unit 55, and the shared nozzle driving unit 56, and the air fan driving unit 45, the hot air generating unit driving unit. 46, the air pump drive unit 55, and the common nozzle drive unit 56 operate the air fan 41, the hot air generation unit 44, the air pump 51, and the nozzle moving mechanism 52 based on the control of the calculation unit 61, respectively. Although not shown in FIG. 7, it goes without saying that the control unit 60A having the above-described configuration is configured to control the washing water jetting unit 30 (see FIG. 4).

[Cleaning and drying operations using sanitary cleaning equipment]
Next, specific cleaning operation and drying operation control of the sanitary washing apparatus 101 will be described with reference to FIGS. FIG. 8 is a time chart showing an example of control of the cleaning operation and the drying operation in the sanitary cleaning apparatus 101. FIGS. 9A to 9C show an example of a cleaning operation (FIG. 9A) and an air injection operation (FIGS. 9B and 9C) by the common nozzle unit 20 included in the sanitary cleaning device 101. FIG. It is typical sectional drawing. 10A to 10C show an example of a cleaning operation (FIG. 10A) and an air injection operation (FIGS. 10B and 10C) by the common nozzle unit 20 provided in the sanitary cleaning device 101. It is a partial side view. FIG. 11 and FIG. 12 are schematic diagrams illustrating a movement path of the air ejection port 21 when the common nozzle unit 20 performs an air ejection operation.

  The drying operation in the present embodiment is performed by selecting the “rapid drying operation” operation mode by operating the drying mode switch 220a among the switches of the remote control unit 120, and the hot air temperature adjustment switch 240. The case where is operated and the temperature setting is set to the “medium” level will be described. This “rapid drying operation” is an operation mode in which air is injected onto the surface to be dried by the air injection unit 50 while the hot air blown by the hot air drying unit 40 is attracted by the air.

  First, in a state where the remote control unit 120 has not been operated yet (elapsed time T0), as shown in “IV. Nozzle front-rear direction position” in FIG. . Further, as shown in “V. Nozzle left-right position” in FIG. 8, the shared nozzle portion 20 is at the center position. “V. Nozzle left-right direction position” is detected by a nozzle left-right direction position sensor (not shown) provided in the nozzle moving mechanism 52, and when located at the center position, the air injection port 21 ( The surface on which the washing water jet 22) is formed is set to have an angle corresponding to the detection reference position of the nozzle lateral position sensor. This set angle is a central angle that is a reference in the left-right direction, and the discharge angles of the air injection port 21 and the cleaning water discharge port 22 are set to be upward.

Next, when the user operates the butt switch 212 of the remote control unit 120 (elapsed time T
1) As shown in “II. On-off valve” in FIG. 8, the on-off valve 34 of the washing water ejection unit 30 is opened by the control unit 60 </ b> A, and tap water flows into the hot water heating unit 31. When the hot water heating unit 31 detects a water flow with a built-in flow sensor (not shown), the control unit 60A starts energization of the hot water heating unit 31 as shown in “I. Hot water heating unit” in FIG. Heated hot water begins to be supplied. At this time, since the switching valve 32 of the flush water injection unit 30 is set on the drain pipe 27 side connected to the toilet 103, hot water that is not sufficiently heated is discharged into the toilet 130.

  Next, when the temperature of the hot water supplied from the hot water heating unit 31 (temperature of the hot water) reaches a preset temperature value (for example, 36 ° C.) (elapsed time T2), “IV. Nozzle front-rear direction position” in FIG. As shown in FIG. 6, the control unit 60 </ b> A operates the first drive motor 53 to advance the shared nozzle unit 20, and causes the tip of the common nozzle unit 20 to reach a “center position” (for example, 100 mm forward).

  Thereafter, as shown in “III. Switching valve” in FIG. 8, the control unit 60 </ b> A switches the switching valve 32 to the cleaning water pipe 26 on the shared nozzle unit 20 side (elapsed time T <b> 3). Hot water is jetted out ("wet washing" operation). Electric power is supplied to the hot water heating unit 31 by using a known control method (PID control, FF control) so that a detection temperature of a hot water temperature sensor (not shown) that detects the hot water temperature becomes a set value (for example, 40 ° C.). Done. Further, the flow rate of the hot water is adjusted to the user's favorite amount by adjusting the valve opening degree of the switching valve 32.

  In this “wet washing” operation, as shown in FIGS. 9A and 10A, hot water is jetted from the washing water jet port 22 of the common nozzle unit 20 toward the surface to be cleaned of the user 400. However, looking at the wet state of the surface to be cleaned, water droplets flow not only to the central part where the cleaning water directly hits but also to the peripheral part, so the local part and its peripheral part (surface to be cleaned f in the figure) It is in a wet state. In FIG. 9A, the cross section of the toilet seat 130 and the toilet 103 is only the outer shape. For example, the toilet seat 130 is not illustrated even if it has a configuration including a heater or the like inside.

  Next, when the “wet washing” operation is finished and the user operates the stop switch 211 of the remote control unit 120 (elapsed time T4), the “III. Switching valve” and “I. hot water heating unit” in FIG. As shown, the control unit 60A switches the switching valve 32 from the flush water pipe 26 on the shared nozzle unit 20 side to the drain pipe 27 on the toilet 103 side, and ejects hot water from the flush water outlet 22 of the shared nozzle unit 20. At the same time as stopping, energization to the hot water heating unit 31 is stopped, the first drive motor 53 is reversed, and the common nozzle unit 20 is retracted to the storage position.

  Then, as shown in “II. On-off valve” in FIG. 8, the control unit 60A closes the on-off valve 34 to shut off the water flow to the washing water ejection unit 30 and finish the washing operation (elapsed time T5). . At this time, as shown in “IV. Nozzle front-rear direction position” in FIG. 8, the shared nozzle unit 20 returns to the storage position (0 mm).

  In this embodiment, the “wet washing” operation has been described, but the basic sequence is the same when the bidet switch 213 of the remote control unit 120 is operated to perform the “bidet washing” operation. In the case of the “bidet cleaning” operation, the setting of the position of the common nozzle unit 20 corresponding to the bidet and the flow rate of the cleaning water is changed.

Next, when the user operates the drying switch 214 of the remote control unit 120 (elapsed time T6), as shown in “VIII. Hot air generation unit” in FIG. 44 is energized, and the temperature rise of the hot air generator 44 is started. As described above, since the operation of the hot air generation unit 44 is started before the operation of the air fan 41 is started, the hot air generation unit 44 is heated in a state where heat radiation is low. The temperature can be increased at high speed.

  At this time (elapsed time T6), as shown in “VI. Air pump” in FIG. 8, the control unit 60A causes the air pump 51 to start for a short time (for example, 1 second) simultaneously with the start of the operation of the hot air generation unit 44. It is made to operate and air is ejected from the air injection port 21 of the common nozzle part 20 for a moment. By this operation, water droplets attached to the surface of the shared nozzle portion 20 are blown off in a state where the shared nozzle portion 20 is in the position accommodated in the main body portion 110, thereby preventing reattachment of water droplets to the user. Can do.

  Next, as shown in “VII. Air Fan” in FIG. 8, the control unit 60 </ b> A starts the operation of the air fan 41 (elapsed time T <b> 7), and thereby hot air blows out from the hot air blowing port 42. Since the temperature of the hot air passes through the hot air generator 44 heated at a high speed, the temperature has reached a predetermined high temperature from the beginning of the air. Moreover, since the hot air production | generation part 44 at this time is controlled by 60 A of control parts, after correction | amending the ventilation temperature by the ventilation temperature correction | amendment part 63 so that it may mention later, it is high temperature (for example, 60 degrees). Hot air will be blown. This warm air is blown from the warm air blowing port 42 to almost the entire surface to be dried of the user.

  Thereafter, as shown in “IV. Nozzle front-rear direction position” in FIG. 8, the control unit 60A operates the first drive motor 53 to advance the shared nozzle unit 20 to the most advanced position (for example, 150 mm forward). However, as shown in “V. Nozzle left-right direction position” in FIG. 8, the second drive motor 54 is operated to change the left-right angle of the common nozzle 20 to the right end angle (for example, + 50 °).

  Thereafter, as shown in “VI. Air pump” in FIG. 8, the control unit 60A operates the air pump 51 (elapsed time T8), and starts air injection from the air injection port 21 to the surface to be dried. Then, as shown in “IV. Nozzle front-rear direction position” and “V. Nozzle left-right direction position” in FIG. 8, the control unit 60A rotates the second drive motor 54 and the first drive motor 53 in the nozzle moving mechanism 52. The direction and the rotation speed are controlled, and the common nozzle unit 20 is reciprocated back and forth at a high speed within a predetermined range (for example, 50 to 150 mm forward), and the angle range in the horizontal direction is changed from the right end angle to the right predetermined angle (for example +50). Slowly move from 0 ° to + 20 ° towards the central angle. This step is referred to as an air injection first step.

  In this air injection first step, the air jet from the common nozzle part 20 gradually approaches the center part while reciprocating back and forth from a predetermined position on the right side of the surface to be dried of the user. . This jet of air is drawn with a locus as shown in FIG. FIG. 11 is a view of the toilet seat 130 and the toilet 103 as viewed from above. In the toilet 103 that can be seen from the opening of the toilet seat 130, there is a virtual region that becomes the buttocks (and the base of the leg) of the user 400. A surface to be dried F, which is a square virtual region indicated by a two-dot chain line in the figure, is shown in the virtual region serving as the user 400 as indicated by a broken line. As shown by an arrow P1 in FIG. 11, a range (air contact range) E in which the air jet abuts on the surface to be dried F reciprocates at high speed in the front-rear direction at the right end of the surface to be dried F (in the drawing). It moves gradually toward the center part G of the surface F to be dried while periodically repeating the directions of arrows D2 and D1 (see FIG. 6). Therefore, the air contact range E moves within the surface to be dried F so as to draw a zigzag movement locus from right to left.

  Further, in the first air injection step, as shown in FIG. 9B, water droplets adhering to the right side of the surface to be dried F of the user 400 are injected from the air injection port 21 of the common nozzle unit 20. The air is blown away while being collected in the central direction (in the direction of arrow D3-1 in the figure, see FIG. 6).

  Thereafter, as shown in “VI. Air pump” in FIG. 8, the control unit 60A temporarily stops the operation of the air pump 51 (elapsed time T9), and as shown in “V. Nozzle left and right position” in FIG. The angle range in the left-right direction of the common nozzle unit 20 is changed to the left end angle (for example, −50 °), the air pump 51 is operated again (elapsed time T10), and air injection is started.

  Thereafter, the control unit 60A reciprocates the common nozzle unit 20 back and forth at a high speed within a predetermined range (for example, from 50 mm to 150 mm forward), as well as the air injection first step, Slowly move from the left end angle to the left side predetermined angle (for example, −50 ° to −20 °) toward the center angle. This step is referred to as an air injection second step.

  In this second step of air injection, the air jet from the common nozzle portion 20 gradually approaches the center portion G while reciprocating in the front-rear direction from a predetermined position on the left side of the user's drying surface F. become. That is, in the air injection second step, as indicated by an arrow P2 in FIG. 11, the air contact range E periodically repeats reciprocating in the front-rear direction at the left end of the surface to be dried F. Since it gradually moves toward the center portion G of the surface to be dried F, in other words, the air contact range E is such that the air contact range E is symmetrical with the zigzag locus indicated by the arrow P1 with respect to the center portion G. It moves to draw a zigzag movement trajectory from right to left.

  Further, in the second air injection step, as shown in FIG. 9C, water droplets adhering to the left side of the surface to be dried F of the user 400 are injected from the air injection port 21 of the shared nozzle unit 20. The air is blown away while being collected in the center direction (in the direction of arrow D3-2 in the figure, see FIG. 6).

  If the air injection first step and the second step are performed, the water droplets remaining on the surface to be dried F are only the front and rear regions around the central portion G.

  That is, since the buttock of the human body is formed with convex portions on both the left and right sides with respect to the washing center portions of the anus and the genital area, when the user sits on the toilet seat portion 130, the washing center portion (the center portion of the surface F to be dried) (See G), the left and right sides are lower. Therefore, since the wetness of the cleaning water tends to spread right and left, if air is first applied toward the center G at the start of the drying operation, the attached water droplets spread greatly to the left and right, and the wet surface F is wetted. The area will expand. Therefore, if the control unit 60A causes the air injection unit 50 to execute the air injection first step and the second step described above, the water droplets can be blown off while preventing the water droplets on the surface to be dried F from spreading from side to side. Therefore, efficient drying is possible.

  Further, when air is first jetted toward the left and right convex portions of the buttock in this way, the user tends to feel cold in the entire buttock, but in this embodiment, as described later, the blast temperature by the blast temperature correcting unit 63 Since the warm air is blown to the warm air drying unit 40 at the same time as the air is jetted, the feeling of cooling can be relieved sufficiently and the comfort of the user can be improved.

  Next, when the air injection second step is completed, the control unit 60A advances the common nozzle unit 20 to the most advanced position as shown in “IV. Nozzle front-rear direction position” in FIG. 8 (elapsed time T11). ). Then, the control unit 60A slowly moves the common nozzle unit 20 backward from the most advanced position toward the center, and reciprocates the angle in the left-right direction from the right end angle to the left end angle at high speed. This step is referred to as an air injection third step.

In this third step of air injection, the jet of air from the common nozzle part 20 gradually approaches the center part G on the rear side while reciprocating in the left-right direction from a predetermined position on the front side of the user's drying surface F. Will come. That is, in the air injection third step, as shown by an arrow P3 in FIG. 12, the air contact range E periodically repeats high-speed reciprocation in the left-right direction at the upper end of the surface to be dried F. It gradually moves toward the center G of the surface to be dried F. Therefore, the air contact range E moves so as to draw a zigzag movement trajectory from the front to the back in the surface to be dried F, and water drops remaining in front of the center portion G of the surface to be dried F are It can be blown away while gathering in the center G direction.

  Thereafter, as shown in “VI. Air pump” in FIG. 8, the control unit 60A temporarily stops the operation of the air pump 51 (elapsed time T12), and as shown in “IV. Nozzle longitudinal direction position” in FIG. The front-rear direction position of the common nozzle unit 20 is moved to a predetermined rear position (for example, 50 mm forward), the air pump 51 is operated again (elapsed time T13), and air injection is started.

  Thereafter, similarly to the third step of air injection, the control unit 60A slowly moves the common nozzle unit 20 forward from the most retracted position toward the center G direction, and the right and left angle is changed from the right end angle to the left end angle. Reciprocate at high speed. This step is referred to as an air injection fourth step.

  In this air injection fourth step, the jet of air from the shared nozzle part 20 gradually approaches the center part G on the front side while reciprocating in the left-right direction from a predetermined position on the rear side F of the user 400 to be dried. I will do it. That is, in the air injection fourth step, as indicated by an arrow P4 in FIG. 12, the air contact range E periodically repeats reciprocating in the front-rear direction at the lower end of the surface to be dried F. Since it gradually moves toward the center portion G of the surface to be dried F, in other words, the air contact range E is such that the air contact range E is symmetrical with the zigzag locus indicated by the arrow P3 with respect to the center portion G. It moves to draw a zigzag movement trajectory from to the front. Therefore, in the fourth step of air injection, water droplets remaining behind the center portion G of the surface to be dried F can be blown off while being collected in the direction of the center portion G.

  If the air injection third step and the fourth step are performed, the water droplets remaining on the surface to be dried F are only near the central portion G.

  Here, in the air injection first step to the fourth step, the control unit 60A determines that the moving direction of the air contact range E with respect to the surface to be dried F is more central than the speed of moving toward the center portion G. The nozzle moving mechanism 52 is controlled so that the moving speed in the direction (crossing direction) intersecting the direction toward the portion G is sufficiently high. Therefore, the air that collides with the surface to be dried F and spreads increases in a component (vertical flow) that flows in a direction perpendicular to the intersecting direction. Therefore, the water droplets adhering between the air contact range E and the central portion G moving in the intersecting direction are moved in the direction toward the central portion G by being pushed by the vertical flow. Therefore, if the air contact range E is gradually brought closer to the central portion G, water droplets are always collected toward the central portion G. Therefore, by executing the air injection first step to the fourth step, water droplets adhering to the surface to be dried F can be quickly and appropriately collected in the central portion G.

  Next, as shown in “VI. Air pump” in FIG. 8, the control unit 60A temporarily stops the operation of the air pump 51 (elapsed time T14), and as shown in “IV. Nozzle longitudinal position” in FIG. Then, the front-rear direction position of the common nozzle portion 20 is moved to a predetermined front position (for example, 130 mm forward), the air pump 51 is operated again (elapsed time T15), and air injection is started.

Thereafter, as shown in “IV. Nozzle front-rear direction position” in FIG. 8, the control unit 60 </ b> A starts to move the common nozzle unit 20 backward from a predetermined position in front, passes through the central part G, and further passes through the central part. Gently move to a predetermined position behind G (for example, 50 mm forward). As shown in “V. Nozzle left / right position” in FIG. 8, the control unit 60 </ b> A reciprocates the left and right angles of the shared nozzle unit 20 at high speed from the right end angle to the left end angle along with the backward movement (FIG. 10 (b) and (c)). This step is referred to as an air injection fifth step.

  In this fifth step of air injection, the jet of air from the common nozzle unit 20 gradually moves from a predetermined position in the front to a predetermined position in the rear while repeating periodic movement in which the surface to be dried F moves in the left-right direction at high speed. And gradually moves to a predetermined position behind the central portion G. Therefore, since the air contact range E moves from the front to the rear through the central portion G on the surface to be dried F, water droplets remaining in the vicinity of the central portion G of the surface to be dried F are almost completely blown off. Is possible.

  In other words, the air injection first step to the fourth step can be referred to as a process of collecting most of the water droplets in the central portion G while blowing off most of the water droplets (water droplet concentration step). It can be said that it is a process (water droplet removal process) of blowing off water droplets remaining in the vicinity of G almost completely. In this embodiment, the air injection first step to the fifth step are executed in the order described above. However, the present invention is not limited to this, and the order of each step may be changed, and some steps are repeated. Alternatively, some steps may be omitted.

  The air injection from the air injection first step to the fifth step is performed by the hot air blowing port 42 of the tip 48 formed in the nozzle guide portion 56b from the hot air supply pipe 43 of the hot air drying unit 40. It is performed simultaneously with the blowing of warm air. Therefore, the warm air from the warm air blowing port 42 of the warm air drying unit 40 is attracted by the flow of pressurized air, and the air is jetted while being warmed. Since the hot air blowing port 42 is formed in the nozzle guide portion 56b and is arranged in the vicinity of the nozzle, it is attracted by the pressurized air (flow) and merges to change its traveling direction, along with the pressurized air. I will head locally.

  Therefore, it is possible to efficiently hit the local area of the user with hot air in addition to the pressurized air. Thereby, the surface to be cleaned can be efficiently dried in a short time without giving excessive coldness and heat to the user.

  Moreover, since warm air can be efficiently pinpointed, it is possible to reduce the air volume by narrowing the range in which the warm air is blown. Therefore, reduce the size and weight of the hot air generator (reduce the size and weight of the hot air fan and reduce noise), reduce the amount of heat in the hot air generator (reducing the amount of heat of the heater, etc., and saving power). You can also.

  Thereafter, as shown in “VI. Air pump” in FIG. 8, the control unit 60A stops the air pump 51 (elapsed time T16), and “IV. Nozzle front-rear direction position” and “V. Nozzle left-right direction position” in FIG. As shown in FIG. 2, the front-rear direction of the common nozzle unit 20 is moved to the storage position, and the left-right direction is returned to the central angle.

  In this way, the removal of water droplets by the air injection unit 50 is finished, and the drying operation is actually finished. Therefore, the user 400 operates the stop switch 211 of the remote operation unit 120, and the control unit 60A In response to this stop command, the operation of the hot air generator 44 is stopped (elapsed time T17) as shown in “VIII. Heater” in FIG. 8, and finally, as shown in “VII. Air fan” in FIG. Thus, by stopping the air fan 41 (elapsed time T18), the remaining heat of the hot air generating unit 44 is reduced. Thus, a series of cleaning operation and drying operation control is completed.

[Control processing of operation of hot air drying unit and air injection unit]
Next, an example of drying operation control by the control unit 60A will be described with reference to FIG. First, the control unit 60A determines whether or not the drying switch 214 of the remote operation unit 120 has been operated (step S101). If not operated (NO in step S101), the determination is repeated. If operated (YES in step S101), first, the hot air generating unit 44 is operated before the air fan 41 (step S102). Thereafter, the air fan 41 is operated (step S103).

  In the present embodiment, by operating the hot air generation unit 44 before the air fan 41 in this way, hot air generation is performed by energizing the hot air generation unit 44 with a large amount of electric power at a time in a state of low heat dissipation. The temperature increase rate of the unit 44 is increased, and therefore the startup time of the hot air generation unit 44 and the rise time to the heating value Tw can be increased.

  Next, 60 A of control parts operate the air injection part 50, and inject air to a to-be-dried surface (step S104). Specifically, as described above, the air injection is performed as the first to fifth air injection steps (FIGS. 8, 9B and 10C, 10B and 10B). see c)).

  Then, the control unit 60A determines whether or not the stop switch 211 of the remote operation unit 120 has been operated (step S105). If not operated (NO in step S105), the determination is repeated, and if operated (YES in step S105), the hot air drying unit 40 (the hot air generating unit 44 and the air fan 41) and the air injection unit 50 are operated. Is stopped and the control is terminated.

  In the control, the air fan 41 and the hot air generation unit 44 may be activated at the same time, and a soft start may be executed in which the amount of air blown by the air fan 41 is gradually increased. In other words, the control unit 60A starts the operation of both the air fan 41 and the hot air generation unit 44 at the same time, but the air fan 41 increases the air flow rate after the start-up stage starts in the hot air generation unit 44. You may control to make it. Also by this, it is possible to speed up the startup time of the hot air generation unit 44 and the rising time to the heating value Tw.

  Further, the drying operation in the present embodiment is not limited to the operation mode (first drying operation mode) in which the hot air drying unit 40 and the air injection unit 50 are simultaneously operated as shown in FIG. 13, but only the air injection unit 50. An operation mode in which only air is sprayed onto the surface to be dried (second drying operation mode) or an operation mode in which only the warm air drying unit 40 is operated to blow only warm air onto the surface to be dried (third drying) Operation mode) can also be selected. Selection of these operation modes is realized by operating the drying mode switches 220a, 220b, and 220c of the remote control unit 120 and the hot air temperature adjustment switch 240.

  Specifically, in the remote control unit 120 shown in FIG. 3A, if the drying mode switch 220a is operated, “rapid drying operation” is selected, so the first drying operation mode shown in FIG. 13 is executed. The drying of the surface to be dried can be completed in a short time. Further, if the drying mode switch 220b is operated, “firmly dry operation” is selected. This “solid drying operation” is basically the same as the first drying operation mode, but is an operation mode that reliably removes water droplets on the surface to be dried by changing the operation time longer.

Further, if the drying mode switch 220c is operated, “warm air drying operation” is selected, so that the air injection unit 50 does not operate, only the hot air drying unit 40 operates, and the third drying operation mode is executed. The However, in the third drying operation mode, only warm air hits the surface to be dried. Therefore, in the target temperature correction processing by the air temperature correction unit 63, each setting data (time setting in the first to fourth stages, air temperature setting value) It is preferable to change Ts and the transient coefficient D) from the setting data of the first drying operation mode. Specifically, in the first drying operation mode, air from the air injection unit 50 hits the surface to be dried, and thus the target temperature (set value Ts) is corrected so that the air blowing temperature becomes high. In the third drying operation mode in which does not operate, the target temperature (set value Ts) may be set low considering that the air to be dried is not cooled by air.

  If the hot air temperature adjustment switch 240 of the remote control unit 120 shown in FIG. 3B is set to “OFF” and the drying mode switch 220a is operated, the second drying operation mode is selected, and only air is Sprayed onto the surface to be dried. This operation mode is configured to be selected particularly when the temperature is high such as in summer.

[Evaluation of various conditions for target temperature correction processing]
In this embodiment, in order to determine the thermal sensation for the user, a seven-stage thermal sensation index is created, and based on the thermal sensation index, the temperature related to the target temperature correction processing by the blower temperature correction unit 63 Evaluating conditions and elapsed time conditions. This point will be described together with specific test methods and results. FIG. 14 is a graph showing the relationship between the thermal sensation or the air temperature after the start of the blowing of warm air, the upper side shows the relationship between the thermal sensation and the elapsed time, and the lower side shows the air temperature and the elapsed time. Shows the relationship.

  The thermal sensation of human beings is sensitive, and in addition to differing by very subtle conditions, individual differences are also large. Therefore, the present inventors divided the thermal sensation into seven stages, and set a suitable value for the blast temperature described above based on this thermal sensation index. Specifically, the seven levels of indicators are “very hot” “+3”, “hot” “+2”, “warm” “+1”, “neither” “0”, “ “Cool” was evaluated as “−1”, “Cold (cold)” as “−2”, and “Very cold (very cold)” as “−3”.

  And in the sanitary washing apparatus 101 which concerns on this embodiment, room temperature as atmospheric temperature, the ventilation temperature (outlet temperature) in the warm air ventilation opening 42, the ventilation in the edge part by the side of the main-body part 110 side of the toilet seat part 130 are monitored items. Eight items were selected: temperature (toilet seat edge temperature), ventilation temperature in the vicinity of the anus, surface temperature in the buttocks, surface temperature in the vicinity of the anus, power consumption in the hot air generation unit 44, and applied voltage in the hot air generation unit 44.

  Then, in the following procedure, a test for evaluating the relationship between the blowing temperature and the thermal sensation was performed a plurality of times by the same evaluator while measuring the monitor items while changing the conditions.

  The procedure is a test procedure for evaluating the relationship between the rise time of the blowing temperature and the thermal sensation from the start of the drying operation. First, the evaluator was seated on the toilet seat 130 and adjusted so that the initial value of the skin temperature matched the ambient temperature. Next, by performing “wet cleaning”, water droplets from the actual cleaning operation were adhered to the surface to be dried (cleaning for 30 seconds at a cleaning water temperature of 38 ° C. and a cleaning water flow rate of 0.5 liter / min). Then, after making the common nozzle part 20 protrude to an anus position, the air pump 51 was operated and it was set as the standby state of the injection of air from the common nozzle part 20. FIG. After that, the operation of the hot air drying unit 40 was started, and the thermal sensation was evaluated until 60 seconds passed or the evaluator felt hot.

  The conditions changed in the above procedure are as follows. First, the setting of the outlet temperature was changed to 30 ° C., 40 ° C., 50 ° C., 60 ° C., 70 ° C., and 80 ° C., respectively. Moreover, the electric power setting of the warm air production | generation part 44 was tested by 0W, 50W, 100W, 200W, and 400W, respectively. As the drying operation mode, when only warm air is blown (third drying operation mode), when warm air is blown and air is injected (first drying operation mode), and only when air is injected (second drying operation) Mode), and each was also tested. In addition, as a comparison, an experiment was conducted in a dry state without water droplets being attached to the heel portion by spraying. Further, in one evaluation test, the thermal sensation was immediately after start, 5 seconds, 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, and 60 seconds. Evaluation was performed.

In any of the above evaluation tests, the air injection conditions are as follows. The room temperature is in the range of 18-22 ° C., the air flow rate of hot air is 0.3 m ³ / min, the flow rate of air is 15 liters / min, the diameter of the air injection port 21 is 1 mm, The distance from the outlet 21 to the anus was 30 mm, the rocking angle in the left-right direction was ± 60 °, and the reciprocation in the front-rear direction was 2 reciprocations per second.

  FIG. 14 is a graph showing the relationship between the rise time of the blowing temperature and the thermal sensation from the start of the drying operation, which was evaluated by the above procedure. In both the upper and lower graphs in FIG. 14, the two-dot chain line indicates the result when the power setting of the hot air generation unit 44 is 400 W, and the one-dot chain line indicates the case where the power setting of the hot air generation unit 44 is 200 W. The result shows that the long broken line shows the result when the power setting of the hot air generating unit 44 is 100 W, and the short broken line shows the result when the power setting of the hot air generating unit 44 is 50 W. In the upper graph of FIG. 14, the diamond mark indicates the result when the power is 400 W, the circle mark indicates the result when the power setting of the hot air generator 44 is 200 W, and the positive triangle mark Shows the result when the power setting of the hot air generator 44 is 100 W, the square mark shows the result when the power setting of the hot air generator 44 is 50 W, and the inverted triangle mark shows the hot air generation The result when the power setting of the unit 44 is 100 W, that is, when the hot air generating unit 44 is not operating is shown.

  The condition that the user feels at least not cool is a condition that gives a thermal sensation index of −1 or higher. Therefore, from the results shown in FIG. 14, the air temperature is 40 ° C. or higher in 5 seconds (thin broken line in FIG. 14). A condition of 50 ° C. or higher in 10 seconds was derived.

  In addition, since it is assumed that most of the general users do not feel cold if the thermal sensation index is 0 or more, the more preferable condition is that the air temperature is 50 ° C. or more in 5 seconds. The condition was 60 ° C. or more in seconds, but 75 ° C. or less within 10 seconds.

  Thus, in the present embodiment, it is particularly preferable that the heating value Tw at the target temperature is set to be within a range of at least 40 ° C. and 75 ° C. or less. Further, it is particularly preferable that the start-up stage and the heating stage are both set to be within 10 seconds, and the start-up stage is set to have a shorter time (within 5 seconds) than the heating stage. Further, it is particularly preferable that the time from the start of blowing to the end of the transition stage is set within 40 seconds, and the total time of the startup stage and the heating stage is set within 20 seconds.

  Of course, the conditions of the blowing temperature and the elapsed time are not limited to the above ranges, and depending on various conditions such as the specific configuration of the sanitary washing device 10 and the environment of the toilet room to be installed, FIG. It can set suitably with reference to results, such as.

  As described above, in the present embodiment, when air is sprayed from the common nozzle unit 20 onto the surface to be dried, the hot air generated by the hot air drying unit 40 is blown onto the surface to be dried, The target temperature correction process is performed so that the warm air is equal to or higher than the temperature value (cool sensation limit value Tc) at which the user does not feel cold even when the surface to be dried is wet. Therefore, more efficient drying becomes possible, and the user feels almost no cooling feeling and can obtain a good feeling of use.

  In the sanitary washing apparatus 101 according to the present embodiment, the air injection unit 50 includes the air pump 51 and the hot air drying unit 40 includes the air fan 41, but the present invention is limited to this. For example, even a sanitary washing apparatus that does not have the air pump 51 and is dried only by the air fan 41 can obtain the same effect by the same configuration as the present embodiment as long as the hot air generation unit 44 is provided. it can.

  In the present embodiment, the room temperature detection unit 72 detects the room temperature of the toilet room and uses this as the ambient temperature near the surface to be dried. However, the present invention is not limited to this. A temperature detection unit that detects the temperature inside 103 may be provided, and a temperature value obtained from the temperature detection unit may be used as the ambient temperature. As a result, the ambient temperature in the vicinity of the surface to be dried can be detected more accurately, so that the target temperature correction process by the blower temperature correction unit 63 and the control of the hot air drying unit 40 by the control unit 60A are more comfortable for the user. Can be.

(Second Embodiment)
The sanitary washing device according to this embodiment basically has the same configuration as the sanitary washing device 101 described in the first embodiment, but the configuration of the nozzle swinging portion in the common nozzle portion 20 is different. . The configuration of the nozzle swinging portion will be described with reference to FIG. FIG. 15 is a partial perspective view showing the configuration of the shared nozzle part provided in the sanitary washing device according to the present embodiment.

  The oscillating nozzle unit 80 shown in FIG. 15 does not rotate (spin) a cylindrical nozzle in the axial direction as in the nozzle moving unit 57 included in the nozzle moving mechanism 52 of the first embodiment described above. The rear end of the columnar nozzle is fixed and swings so as to swing around the front end side.

  Specifically, the nozzle oscillating unit 80 has a oscillating unit supporting slider 83 as a main body, and a columnar rotary shaft unit 81 and a second drive motor that support the rear end of the nozzle main body 20b on the upper surface thereof. 54, and a downstream portion of the hot air supply pipe 43a in the hot air drying section 40a between the side surface of the shaft portion 81 and the rear end of the nozzle body 20b. Are connected to each other, and a tip portion 48 a of the hot air drying unit 40 a is formed in the shaft portion 81. A warm air supply pipe 44a is connected to the tip 48a. Moreover, the warm air blowing port 42a is formed in the front-end | tip part 48a at the rear end side of the nozzle main body 20b in which the air injection port 21 and the washing water injection port 22 are comprised.

  In addition, since the warm air structure and component structure supplied to the warm air ventilation opening 42a from the warm air drying part 40a are the same as that of 1st Embodiment, the description is abbreviate | omitted.

  Further, the hot air blowing port 42a has a direction in which the warm air flowing out from the hot air blowing port 42a is substantially parallel to the direction of the axis of the nozzle body 20b, and is pressurized air ejected from the air ejection port 21. It is arrange | positioned at the rear end of the nozzle main body 20b so that it may cross with the advancing direction. Thereby, the warm air which comes out of the warm air blowing port 42a formed in the front-end | tip part 48a of the warm air drying part 40a advances along the side surface of a nozzle, and the pressurized air which is ejected from an air outlet (flow) Will be attracted to and change the direction of travel, and will go to the user's local area with pressurized air.

  Further, like the nozzle fixing portion 58a of the nozzle support slider 58 in the first embodiment, the swinging portion support slider 83 is sandwiched between the rail portions 56a and 56a, and the upper surface of the mounting surface 56c is elongated. A rail fitting portion 83a that is slid along the direction is formed (see FIG. 6). Of the upper surface of the swinging portion support slider 83, the portion where the rotating shaft portion 81 is placed is the rail fitting portion below, and the portion where the second drive motor 54 is placed is A guide penetration part 83b that penetrates the slider guide part 57b is formed on the lower side of the mounting surface 56c in the same manner as the slip support slider 58.

The rotary shaft portion 81 has a cylindrical shape provided so that the axial direction is positioned in the normal direction of the upper surface of the swinging portion support slider 83, and the rear end of the nozzle body 20b is formed on a part of the outer periphery thereof as described above. It is fixed. An outer peripheral gear portion 82 a that meshes with the drive gear 82 attached to the rotary shaft of the second drive motor 54 is formed on the lower peripheral surface of the rotary shaft portion 81. The center of the rotating shaft 81 in the axial direction is a cavity, and an axial center 83c extending vertically from the upper surface of the swinging portion support slider 83 passes therethrough. In addition, since the internal structure of the nozzle main body 20b is the same as that of the nozzle main body 20a of 1st Embodiment, the description is abbreviate | omitted.

  The nozzle swinging portion 80 and the nozzle body 20b fixed thereto are provided on the nozzle support portion 55 in place of the nozzle support slider 58, the swinging gear portion 57a, and the nozzle body 20a in the first embodiment. And in this nozzle rocking | swiveling part 80, unlike the nozzle moving part 57 in 1st Embodiment, the nozzle main body 20b is integrally connected to the rotating shaft part 82, and this nozzle main body 20b is shown by the arrow D4. Then, it is swung back and forth so as to be swung around the rotation shaft portion 81 as a starting point. Therefore, the locus drawn by the tip of the nozzle body 20b has a fan shape.

  In the nozzle swinging unit 80, the configuration in which the nozzle body 20b moves forward and backward is the same as that of the nozzle moving mechanism 52 in the first embodiment, but the rotational driving force of the second drive motor 54 for swinging the nozzle body 20b. Is transmitted to the rotary shaft portion 82 via the drive gear 82 and the outer peripheral gear portion 81a, so that the nozzle main body 20b is not rotated by rotating the nozzle main body 20a as in the first embodiment. Is swung to a predetermined angle.

  According to the said structure, the jet of air from the air jet nozzle 21 can be made to eject substantially maintaining perpendicular | vertical with respect to a to-be-dried surface. Therefore, it is possible to improve the action of peeling water droplets adhering to the surface to be dried from the surface to be dried. In addition, it is possible to further suppress the action of moving water droplets to the outside of the surface to be dried, which occurs when air hits the surface to be dried. Therefore, the water droplet concentration process from the air injection first step to the fourth step in the first embodiment can be performed more efficiently.

  Further, as in the first embodiment, the nozzle main body 20b is not rotated, and the nozzle main body 20b is swung around. Therefore, even if the tip of the nozzle main body 20b is swung and the jet of air is moved left and right. The distance until the jet hits the surface to be dried is not greatly separated. Therefore, a jet having a high flow velocity can be applied to the surface to be dried, and the ability to remove water droplets can be further improved.

  The sanitary washing device according to the present invention is an extremely useful invention in the field of a sanitary washing device provided with a drying mechanism that blows air and removes water droplets and blows hot air after washing of local parts and the like. .
