  However, in the conventional configuration, since a plurality of fins 6 are installed in the ventilation path of the fan casing 4, the fins 6 have a large resistance in the ventilation path, so that the wind power of the warm air is reduced and the drying capacity is reduced. It is to reduce.

  Moreover, the fin 6 is installed in the blower outlet, and the warm air blown out from the blower outlet is blown linearly following the direction of the fin 6 and goes straight in the direction of the anus or local part to be dried. It will be. However, since the anus and local part to be dried are in the concave part of the buttocks, the warm air blown from behind obliquely is not directly hit by the convex part of the buttocks, and it is difficult to obtain sufficient drying performance.

  In addition, the wind direction changing function of this prior art document is to change the wind direction periodically in order to avoid the hot air being continuously applied to one place. As a result, the wind direction is changed over a wider range than necessary. There was room for improvement in terms of energy efficiency and drying efficiency.

A casing and a rotation mechanism for rotating the wind direction changing unit at a predetermined angle, wherein the casing opens an intake port in the main body, opens a jet outlet at a lower front surface of the main body, and From the side, A motor, the heater unit, and the wind direction changing unit are sequentially arranged, and the casing is curved at least from the position where the heater unit is disposed toward the air outlet side and from the side of the main body toward the center. The wind direction changing unit is installed in the bending portion, and the control unit controls the turning mechanism to change the angle of the wind direction changing unit, thereby causing hot air to be ejected from the jet outlet. It is possible to change the direction of jetting.

  As a result, the warm air blown by the fan motor and heated by the heater unit forms a curved flow at the curved portion of the air passage, and the curved flow hits the wind direction changing column having a substantially circular cross section. As a result of the Karman vortex, a curved component in the opposite direction is generated, so that the direction of the warm air changes from the upstream side to the downstream side of the wind direction changing column, and the hot air itself has an eddy current component. By adding, it becomes possible to maintain the wind direction changing component even after jetting from the jet outlet, and further, the Karman vortex can equalize the warm air temperature, and the slight resistance of the substantially circular wind direction changing column The air direction can be changed, and the hot air after jetting can easily flow along the recess of the buttocks, and the temperature unevenness of the hot air temperature is eliminated, so that the drying performance can be improved. In addition, since it is possible to change the jet direction of the warm air by changing the angle of the air direction changing unit, the position where the cleaning water adheres (the position to be dried) differs between the butt cleaning and the bidet cleaning. Correspondingly, since it becomes possible to eject hot air in the optimum ejection direction, the drying performance can be further improved.

  According to a second aspect of the invention, in particular, in the first aspect of the invention, the control unit corresponds to the first predetermined angle of the wind direction changing unit corresponding to the drying after the buttocks cleaning and the drying after the bidet cleaning. A second predetermined angle of the wind direction changing unit in advance, and when the user performs a drying operation after buttocks cleaning, the control unit drives the turning mechanism to move the wind direction changing unit to the air direction changing unit. When the user performs a drying operation after cleaning the bidet, the control unit drives the rotating mechanism to control the wind direction changing unit to the second predetermined angle. Thus, it is possible to improve the drying efficiency and usability by recognizing that the position of wetting differs depending on the washing water between the buttocks washing and the bidet washing, and automatically changing the direction of the hot air ejection.

  In the third invention, particularly in the second invention, the user starts the other cleaning within a predetermined time following the buttocks cleaning or the bidet cleaning. When an operation is performed, the control unit gets wet with butt cleaning and bidet cleaning by driving the rotating mechanism so as to periodically change the first predetermined angle and the second predetermined angle. Since a wide range can be automatically and evenly dried, the usability can be further improved.

  In a fourth aspect of the invention, in particular, in any one of the first to third aspects, the operation unit includes an adjustment switch, and a user operates the adjustment switch to arbitrarily change the angle of the wind direction changing unit. By making it possible, the hot air blowing direction can be finely adjusted in an arbitrary direction according to the user's body shape and preferences, and the drying efficiency and usability can be further improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

<2> Configuration of Drying Device FIG. 3 is a perspective view showing the appearance of the drying device in the first embodiment, and FIG. 4 is a cross-sectional view seen from the side of the drying device in the present embodiment. FIG. 6 is a plan view showing the internal structure of the drying device, FIG. 6 is a schematic diagram showing the flow of hot air near the wind direction changing column, and FIG. 7 shows the flow of hot air in the sanitary washing device in the present embodiment. It is a schematic diagram.

  As shown in FIGS. 3, 4, and 5, the drying apparatus 700 mainly includes a casing 701 that forms an air passage therein, a fan motor 702, a heater unit 703, a wind direction changing column 704, and a drying shutter 708. It is comprised as a simple structural member.

  A casing 701 is formed by joining an upper case 701a and a lower case 701b molded with a flame-retardant resin vertically to form a tunnel-shaped cavity, and a substantially square air inlet 705 is opened at the rear end. The front end has a substantially rectangular nozzle 706 opened. The intake port 705 of the casing 701 is disposed in the main body 200 of the sanitary washing device 100, and the jet port 706 is disposed in the lower front portion of the main body 200.

  As shown in FIGS. 3 and 4, the spray outlet 706 of the drying device 700 is provided with a drying shutter 708 that can be freely opened and closed. When the drying device 700 is not used, the drying shutter 708 is closed and used during defecation. It is configured such that filth and washing water do not directly reach the jet outlet 706, and is configured to be opened by wind pressure when the drying apparatus 700 is used. Further, the drying shutter 708 is configured to be detachable so that cleaning can be performed when dirt is attached.

  As shown in the figure, a fan motor 702, a heater unit 703, and a wind direction changing column 704 are sequentially arranged inside the casing 701 from the air inlet 705 side. The air passage formed by the casing 701 is formed such that the cross-sectional area is gradually reduced from the installation position of the fan motor 702 to the jet outlet 706 side.

  As shown in FIG. 4, the ejection port 706 side from the installation position of the fan motor 702 is inclined downward to form a substantially horizontal air path in the immediate vicinity of the ejection port 706. Further, as shown in FIG. 5, in a plan view, the jet outlet 706 side from the installation position of the heater unit 703 forms a curved portion 707 that is curved from the side of the main body 200 toward the center. Reference numeral 704 denotes a bending portion 707.

  An axial fan motor 702 is disposed in the vicinity of the air inlet 705 of the casing 701. The fan motor 702 is horizontally held between the upper case 701a and the lower case 701b. Both the upper case 701a and the lower case 701b are bent downward on the jet outlet 706 side from the installation position of the fan motor 702. In particular, the upper case 701a is bent larger than the lower case 701b. The bottom surface of the installation position of the fan motor 702 of the lower case 701b is configured to be located above the upper end of the jet outlet 706.

  A heater unit 703 is installed between the bent upper case 701a and lower case 701b. The heater unit 703 has a larger opening area on the fan motor 702 side than on the jet outlet 706 side.

On the curved portion 707 of the lower case 701b, four wind direction changing columns 704 having a diameter of about 2 mm are erected in an integrated manner in the vertical direction at equal intervals of about 6 mm. In addition, the four air direction changing columns 704 form an angle of about 30 degrees with respect to the ejection port 706 so that the central side near the cleaning nozzle 103 is closer to the heater unit 703, and the air direction changing columns 704 are in a straight line. They are arranged side by side.

  The heater unit 703 includes a heater wire (not shown) of about 400 W that is a heating means, a thermal fuse 703a that operates at 110 ° C., and a thermostat that operates at 86 ° C. The outer shell is covered with a cover mica 703c. It has been broken.

  A heater wire (not shown) formed in a spiral shape is disposed in the vicinity of the outer periphery inside the cover mica 703c, and is located near the fan motor 702 in the center of the spiral of the heater wire (not shown). A thermal fuse 703a is disposed at the rear, and a thermostat 703b is disposed at the front. A heater wire (not shown), the thermal fuse 703a, and the thermostat 703b are electrically connected in series.

  The thermal fuse 703a and the thermostat 703b are overheat prevention means for preventing the internal temperature from rising abnormally. When an abnormal rise occurs due to a failure of the fan motor 702 resulting in a locked state or the like, as a first step, the thermostat 703b, which is a return-type overheat prevention means, operates first to energize the heater. For example, when the thermostat 703b is not activated due to a failure of the thermostat 703b, as a second step, the non-returnable thermal fuse 703a is blown to cut off the energization to the heater wire (not shown), thereby generating smoke. And fire is not generated.

  About the sanitary washing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the user enters the toilet room and the seating sensor 204 detects the user seated on the toilet seat 400, the operation switch 201 enables the operation of the cleaning function and the drying function.

  When the user performs the cleaning operation with the operation switch 202 after the stool is completed, the cleaning nozzle 104 advances from the main body 200, and the user's local area is cleaned by ejecting the cleaning water. The cleaning nozzle 104 is stored in the main body 200.

  Next, when the user performs a drying operation using the operation switch 202 as an operation unit, the control unit 900 controls the energization to the fan motor 702 and the heater unit 703 of the drying apparatus 700 to start the drying operation. The air sucked from the air inlet 705 by the fan motor 702 is blown to the heater unit 703, and the warm air heated by the heater unit 703 is jetted from the jet outlet 706 toward the user's local area, and the user who gets wet by washing Dry the local area.

  6 and 7 show the flow of hot air and the target position A. A curved flow is formed in the curved portion 707 of the air passage, and the Karman vortex is generated downstream of the wind direction changing column 704 when the curved flow hits the wind direction changing column 704. The Karman vortex generates a curved component in the opposite direction in the warm air. The warm air is less curved at the downstream side of the wind direction changing column 704 than the upstream side, and the vortex component is added to the warm air itself. By adding the eddy current component, the wind direction changing component is maintained even after jetting from the jet outlet 706, and the hot air after jetting is at the target position so as to draw a curve opposite to the curve of the curved portion 707. It flows toward.

  When the warm air flows in a reverse curve, it flows from the center behind the seated user toward the front, and the warm air easily flows along the recess in the heel where the user is locally located. Contributes to improving drying performance.

In the present embodiment, the target position A of the warm air ejected from the ejection port 706 is set such that the distance from the rear end of the toilet seat 400 is about 65 mm to about 25 mm as shown in FIG. This corresponds to the local position when the user is seated on the toilet seat 400.

  As described above, in the present embodiment, the four wind direction changing columns 704 are installed so as to be aligned with the curved portion 707, so that the wind direction can be changed by a slight resistance of the wind direction changing column 704. At the same time, the hot air after jetting while maintaining the curved component is easy to flow along the recess of the buttocks, and further, the temperature unevenness of the hot air temperature is eliminated, so that the drying performance can be improved.

  In the present embodiment, four wind direction changing columns 704 are installed on the curved portion 707. However, the number of installed columns is not limited to four, and even one can exert the effect of changing the wind direction. Therefore, the number and thickness of the wind direction changing columns 704 can be changed at any time.

  In the present embodiment, the four wind direction changing columns 704 are installed with an inclination of about 30 degrees with respect to the jet outlet 706. However, the installation angle is not limited to 30 degrees, and the shape of the toilet seat 400 is not limited. If the target position is different due to a difference in the other, it is possible to adopt another installation angle. Moreover, when the shape of the casing 701 is different, examination of another installation angle is essential.

  In the present embodiment, the thicknesses of the four wind direction changing columns 704 are all equal to 2 mm in diameter. However, the present invention is not limited to this, and at least one of these diameters may be different. In particular, by increasing the diameter of the wind direction changing column 704 arranged on the most central side of the curved portion 707, the wind direction on the central side is greatly changed. Hot air can be reached with high accuracy.

  In the present embodiment, all the wind direction changing columns 704 are formed integrally with the lower case 701b of the casing 701. However, the present invention is not limited to this, and can be formed integrally with the upper case 701b. It may be formed separately from the casing 701 and installed in the casing 701.

(Embodiment 2)
FIG. 8 is a cross-sectional view seen from the side of the drying apparatus according to Embodiment 2 of the present invention, and FIG. 9 is a plan view showing the internal structure of the drying apparatus.

  This embodiment is different from the first embodiment in that a wind direction changing column unit 710 in which four wind direction changing columns 704 having a diameter of about 2 mm are integrally provided on a flat base 709 at an equal interval of about 6 mm is formed. A rotation mechanism 711 having a motor (not shown), a speed reduction mechanism (not shown), and a rotation angle detection means (not shown) is installed on the lower side of the lower case 701b, and an opening provided in the lower case 701b ( The rotating shaft (not shown) of the wind direction changing unit 710 is fastened to the rotating mechanism 711 via the rotating mechanism 711 and the wind direction changing unit 710 is rotated by the rotating mechanism 711 to change the angle of the wind direction changing column 704. The configuration can be changed. Thereby, it became possible to freely change the jet direction of the hot air by controlling the rotation mechanism 711 by the control unit 900.

  In addition, the thing of the same code | symbol as Embodiment 1 has the same structure, and abbreviate | omits description.

  About the sanitary washing apparatus in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

When the user finishes the butt cleaning using the butt cleaning nozzle portion of the cleaning nozzle unit 104 and then performs a drying operation with the operation switch 202, the control unit 900 causes the fan motor 702 and the heater unit 703 of the drying device 700 to be dried. Controls energization to start drying operation. The air sucked by the fan motor 702 from the air inlet 701 is blown to the heater unit 703, and the warm air heated by the heater unit 703 is jetted from the jet outlet 706, and the user's local area wet by the cleaning is dried.

  At this time, the control unit 900 performs a signal from the rotation angle detection unit of the rotation mechanism 711 so that the wind direction change column 704 of the wind direction change unit 710 forms an angle of about 30 degrees with respect to the jet port 706 according to preset control conditions. As shown in FIG. 7, the hot air jetted from the jet outlet 706 has a distance from the rear end of the toilet seat 400 ranging from about 65 mm to about 25 mm as shown in FIG. Warm air is spouted out.

  On the other hand, when the user finishes the bidet cleaning using the bidet cleaning nozzle portion of the cleaning nozzle unit 104 and then performs a drying operation with the operation switch 202, the control unit 900 performs the wind direction changing unit 710 according to preset control conditions. The angle of the air is changed by a signal from the rotation angle detecting means of the rotation mechanism 711 so that the wind direction changing column 704 forms an angle of about 29 degrees with respect to the outlet 706, and the warm air blown from the outlet 706 Warm air is jetted toward a target position in the range of about 80 mm to about 25 mm from the rear end of the hole of the toilet seat 400 that is about 15 mm ahead of the cleaning.

  In addition, after the user finishes ass cleaning or bidet cleaning, the other cleaning is started continuously within a predetermined time (in this embodiment, 5 seconds), and ass cleaning or bidet cleaning is continued. Then, when the drying operation is performed by the operation switch 201, the control unit 900 periodically rotates the rotation mechanism 711 in the range of 29 degrees to 30 degrees, and the warm air is washed both in the hips and the bidet. It spouts while fluctuating periodically toward the target position.

  In addition, by operating an adjustment switch (not shown) provided on the operation unit 203, the user has an adjustment function to arbitrarily change the angle of the wind direction changing unit 710. Depending on the body shape and preference of the user, The jet direction of the warm air can be finely adjusted in an arbitrary direction.

  As described above, the sanitary washing device according to the second embodiment recognizes that the position of getting wet by washing water differs between the buttocks washing and the bidet washing, and automatically changes the direction of the hot air ejection. Drying efficiency and usability can be improved.

  In addition, since the hot air blowing direction can be changed according to the body shape and preferences of the user, the drying efficiency can be further increased.

  In the present embodiment, four wind direction changing columns 704 are installed in the wind direction changing column unit 710. However, the number of installed units is not limited to four, and even one can exert the effect of changing the wind direction. Since it is possible, the number and thickness of the wind direction change pillars 704 can be changed at any time.

  In the present embodiment, the thicknesses of the four wind direction changing columns 704 are all equal to 2 mm in diameter. However, the present invention is not limited to this, and at least one of these diameters may be different. In particular, by increasing the diameter of the wind direction changing column 704 arranged on the most central side of the curved portion 707, the wind direction on the central side is greatly changed. Hot air can be reached with high accuracy.

  As described above, since the sanitary washing device according to the present invention can change the wind direction with a slight resistance, it can be applied to other blower applications.
