Although not shown, the cleaning nozzle 201 has a buttock cleaning nozzle portion for cleaning the buttocks and a bidet nozzle portion for cleaning the female portion.

In addition, the drying unit blows out warm air toward the wet wetted portion with the washing water, thereby drying the wetted portion.

The remote controller 500 is equipped with a some operation switch. The remote controller 500 is attached to a place such as a wall surface of a toilet room where a user seated on the toilet seat 300 is operable, and receives a signal for operating each function of the sanitary washing apparatus 100 according to the user's input. Send to 200.

The human body detecting sensor 600 is attached to the wall surface of the toilet room or the like. The human body detection sensor 600 is, for example, a reflective infrared sensor, and detects that the user has entered the toilet room when detecting infrared rays reflected from the human body.

The control part of the main body part 200 operates each part of the sanitary washing apparatus 100 based on the signals transmitted from the remote controller 500, the human body detection sensor 600, the operation unit 203, and the seating sensor 202. To control.

Next, the structure of the toilet seat 300 is demonstrated. 7 illustrates a perspective view of the assembled state of the toilet seat 300, and FIG. 8 illustrates an exploded perspective view of the toilet seat 300. FIG. 9 is a cross-sectional view taken along the line B-B of FIG. 7, and FIG. 10 is a cross-sectional view taken along the line C-C of FIG. 7.

The toilet seat 300 is comprised using the upper toilet seat casing 310, the toilet seat heater 350, and the lower toilet seat casing 320 as main components. The toilet seat heater 350, which is a heating unit, is built in the toilet seat 300. Hereinafter, the front side is the whole of the toilet seat 300 from the seated user, and the rear side is the rear part of the toilet seat 300 from the seated user. The toilet seat 300 is rotatably supported by having the arm part 322 in a rear part as shown in FIG. 7, and engaging the arm part 322 with the rotating mechanism (not shown) of the main body part 200. As shown in FIG. .

The annular upper toilet seat casing 310 is formed by, for example, molding an aluminum plate having a thickness of about 1 mm by press working or the like. Although it is formed in substantially ellipse shape in FIG. 8, the whole may be a horseshoe-shaped shape cut | disconnected in the middle. An alumite layer and a surface cosmetic layer are provided on the surface of the upper toilet seat casing 310, and a polyester powder coating film having insulation and heat resistance is formed on the rear surface.

Instead of the aluminum plate, another metal having good thermal conduction, such as a plate material such as copper or stainless steel or a molded product of magnesium alloy, may be used. In addition, the surface treatment performed on an aluminum plate is not limited to the said specification, It can also select other chemical treatment, coating other than using the acrylic or urethane type coating, or laminating a film.

In the upper toilet seat casing 310, the back part 312 is continuously formed in the rear part of the seating surface 311 which is substantially elliptical. In addition, when the upper toilet seat casing 310 is formed in a horseshoe shape, the seating surface 311 also becomes a horseshoe shape, and this shape is also included in the annular shape in elliptical shape.

The seating surface 311 has an inclination higher in the outer peripheral part 311b than the inner peripheral part 311a. In other words, the seating surface 311 has a curved surface that is convex upward. As shown in FIG. 9, the height difference H1 of the inner peripheral part 311a and the outer peripheral part 311b in the side part of the seating surface 311 is about 25 mm, for example, and is smaller than this in all.

The back part 312 and the seating surface 311 are connected by the continuous concave curved surface, and the upper part of the back part 312 becomes an inclined surface. The upper edge 312a of the back 312 has a large curve near the horizontal line, and the width of the back 312 is approximately the same as the width of the seating surface 311.

As shown in FIG. 10, the height difference H2 of the inner peripheral part 311a in the rear part of the seating surface 311 and the upper edge 312a of the back part 312 is about 80 mm, and the height difference of the back part 312 is (H2) is about 3.2 times the height difference H1 of the seating surface 311 side part.

The toilet seat heater 350 is formed in substantially horseshoe shape in which one part of the whole oval shape was cut off. The toilet seat heater 350 is adhered to the rear surface of the upper toilet seat casing 310. Although not shown in figure, the toilet seat heater 350 is comprised by meandering and installing a linear heater between two metal foils which consist of aluminum. The seat heater 350 is provided with a linear heater to heat the seating surface 311 and the back 312, and in particular, changes the density according to the place so that the thigh and buttocks of the seated user are comfortably heated. Is installed.

The lower toilet seat casing 320 that is annular in an approximately elliptic shape is formed of a synthetic resin. In addition, when the upper toilet seat casing 310 is formed in a horseshoe shape, the lower toilet seat casing 320 is also formed in a horseshoe shape. The lower toilet seat casing 320 is a molded article using a resin material. The lower toilet seat casing 320 is composed of a main body portion 321 and a pair of arm portions 322. The planar shape of the body portion 321 is approximately the same shape as the upper toilet seat casing 310. The arm portion 322 protrudes obliquely upward on both rear sides of the main body portion 321. The upper toilet seat casing 310 and the lower toilet seat casing 320 are coupled to an inner circumferential portion 311a and an outer circumferential portion 311b. The water-tight portion is formed in the coupling portion by rubber or resin packing or adhesive sealing agent.

As shown in FIG. 5, the upper surface of the main body 200 is slightly higher than the upper edge 312a of the back 312, and the main body 200 starting from the upper edge 312a of the back 312. The elevation angle (D) to the upper surface of is 38 degrees. When not in use, the toilet seat 300 is covered with a lid 400 from above. As shown in FIG. 2, since the lid 400 covers the upper surface and the side surface of the upper toilet seat casing 310 which stuck the toilet seat heater 350 to the back surface in particular, it suppresses the heat radiation in air | atmosphere, and has an energy saving effect. Can be improved.

Next, the posture of the body when the user sits on the toilet seat 300 will be described. 11 and 12 are schematic diagrams showing a state where the user is seated on the toilet seat.

As shown in FIG. 11, when the user seats at the optimum position of the toilet seat 300, the thigh of the user contacts the seating surface 311, and the rear part of the buttocks contacts the back 312. Both the seating surface 311 and the back part 312 are heated up by the toilet seat heater 350, and a user does not feel cold. That is, the seat heater 350 is preferably configured to be capable of heating the seating surface 311 and the back 312. By this structure, it becomes possible to heat all the parts which a back part directly contacts, and the comfortable toilet seat 300 can be realized.

However, when the user seats on the toilet seat 300, there are few cases where the user can sit at the optimum position from the beginning, and once the user seats, it is common to move to the optimal position while sitting. As shown in Fig. 9, the seating surface 311 of the toilet seat 300 is preferably an upwardly convex curved surface having a lower inclination than the outer peripheral portion. By this curved shape, the user can move the left and right movements relatively easily even while seated. In addition, since the toilet seat 300 has a low inclination of the inner circumference, the user can easily sit in the center.

On the other hand, if the user wants to move to the rear of the toilet seat 300, the back of the buttocks contact the back 312. As such, the back 312 restricts the user from moving further back. For this reason, the buttocks are not in contact with the main body 200, and the user does not feel uncomfortable such as coldness. That is, the back 312 restrains the buttocks of the user from contacting the main body 200 by restricting movement of the seated user to the rear of the buttocks. In addition, by forming the seating surface 311 and the back part 312 continuously, it becomes possible to easily clean the part which a body directly contacts, and can be made a comfortable and sanitary toilet seat. In particular, by forming the curved portion 312b of the dorsal portion 312 into a concave curved surface, it is possible to more reliably regulate the movement to the rear of the buttocks.

In addition, when the seating sensor 202 is provided in the surface of the main-body part 200, the back part 312 suppresses that a buttocks and a recess of a user contact a seating sensor 202. Accordingly, even when the user does not sit at the optimal seating position or inadvertently moves the body at the time of seating, the buttocks do not touch the seating sensor 202 inadvertently. For this reason, a reliable seating detection can be performed, without having the buttocks etc. contact with the seating sensor 202, and a seating detection is impaired. Moreover, since the seating sensor 202 can be formed in substantially the same surface as the main-body part 200, the cleaning property of the main-body part 200 is not impaired.

Moreover, it is preferable that the upper edge 312a of the back part 312 becomes a big curve near a horizontal line, and the width | variety of the upper edge 312a is substantially the same dimension as the width of the seating surface 311. As shown in FIG. By this shape, the back part 312 opposes over the full width of the back of the buttocks of the user, and regulates the movement backward in the range of the predetermined height. For this reason, contact of the buttocks with the main body 200 can be suppressed more reliably. In addition, the upper edge 312a may be a horizontal straight line or other shapes, and as shown in FIG. 4, the back portion 312 may cover the entire front inclination portion 200a under the main body 200. Thus, the toilet seat 300 has an oval-shaped seating surface 311 which is annular in shape, and is provided continuously in the rear of the seating surface 311 and has a curved portion 312b extending upwardly inclined upward.

In particular, with respect to the height difference H1 of the side part of the toilet seat 300 shown in FIG. 9, the height difference H2 of the inner peripheral part of the toilet seat 300 shown in FIG. 10 and the upper edge 312a of the back part 312 is It is preferable that it is three times or more. In this way, the user in the seated state can be almost restricted from moving backward. Moreover, when the height difference H2 is made into 5 times or less of the height difference H1, the shape of the toilet seat 300 becomes compact and productability becomes high.

In addition, when moving backward by force or when an obese person is seated, as shown in FIG. 12, a part of a body may be in the state which protrudes behind the back part 312. As shown in FIG. In this case, it is preferable that the main body 200 is not disposed in a range above 45 degrees of the elevation angle D starting from the upper edge of the back 312 described in FIG. 5. That is, it is preferable to arrange | position the main body part 200 only in the range whose elevation angle D starting from the upper edge of the back part 312 is 45 degrees or less. By such a configuration, the buttocks are hardly contacted with the seating sensor 202 mounted so as to be almost the same surface as the surface of the main body 200 even when the user slides the buttocks back surface to the back 312.

In this embodiment, the elevation angle D which the upper edge 312a of the back part 312 of the toilet seat 300 and the upper surface of the main body part 200 make is 38 degree, and the main body part 200 is 45 degree walk They do not exist in the above range. For this reason, the body rear part hardly contacts the main body part 200.

Next, the more preferable shape of the toilet seat 300 is demonstrated using FIGS. 13-15. FIG. 13 is a side view of the toilet seat 300, and FIG. 14 and FIG. 15 are enlarged sectional views of the toilet seat 300, FIG. 14 shows the vicinity of the inner circumference 311a in FIG. 9 and FIG. 15 shows the vicinity of the outer circumference 311b. have.

As shown in FIG. 13, the upper toilet seat casing 310 has a rib 313 that is provided upright from the seating surface 311 and the back 312 toward the lower toilet seat casing 320. And the height H4 of the rib 313 in the back part 312 is lower than the height H3 of the rib 313 in the seating surface 311. When the seat heater 350 heats the seating surface 311 and the back part 312, since the heat dissipation area is large, power consumption increases. The upper toilet seat casing 310 supports the weight of the user, most of which is supported by the seating surface 311. For this reason, in the back part 312, even if height H4 of the rib 313 is lower than height H3 in the seating surface 311, there is no problem in strength. The heat dissipation area can be reduced by lowering the height H4 of the rib 313 in the back portion 312, and power consumption can be reduced.

Moreover, it is preferable to make height H3 of the rib 313 in the seating surface 311 into 5 mm or more and 40 mm or less, More preferably, it is 15 mm or more and 20 mm or less. By setting the height H3 of the rib 313 in such a range, the upper toilet seat casing 310 heated by the toilet seat heater 350 reaches the user's buttocks while ensuring the strength on the seating surface 311. Can cover. For this reason, it becomes possible to heat all the parts which a buttocks contact directly, and can realize a comfortable toilet seat.

And it is preferable to protrude the upper toilet seat casing 310 in the horizontal direction from the lower toilet seat casing 320 in the state in which the toilet seat 300 is mounted on the toilet seat 700, as shown to FIG. 14, FIG. By such a configuration, even when an obese user sits on the toilet seat 300, it is possible to heat all the portions where the buttocks are in direct contact with each other, thereby realizing a comfortable toilet seat.

Next, the operation and action of the sanitary washing apparatus 100 will be described. At the time of non-use, the lid 400 is closed and covers the upper surface of the toilet seat 300 and the side surface of the upper toilet seat casing 310. When room temperature, such as a winter system, is low, the toilet seat heater 350 is energized by control of the control part built into the main-body part 200. FIG. For this purpose, the toilet seat 300 is temperature-controlled so that it may be about 18 degreeC, for example. The temperature at this time is called an atmospheric temperature. In addition, when the room temperature, such as summer, is high, since the temperature of the toilet seat 300 becomes high, the electricity supply to the toilet seat heater 350 is not performed.

Here, when a user operates the toilet seat temperature adjustment switch (not shown) of the remote controller 500, a set temperature is transmitted to a control part. The control unit stores the set temperature received from the remote controller 500 in a storage unit (not shown).

When the user enters the toilet room, the human body sensor 600 detects the user's entrance. In this way, the user's entrance detection signal is transmitted to the control unit.

When the control unit detects the entrance to the user's toilet room by the entrance detection signal from the human body detection sensor 600, the control unit opens the lid 400 and the toilet seat heater 350 based on the stored set temperature. Select a specific control pattern for driving of. Based on the selected control pattern and time information obtained by the timekeeping unit (not shown), the control unit controls the driving of the toilet seat heater 350. Thereby, the toilet seat heater 350 is drive-up temperature, and the temperature of the toilet seat 300 immediately rises to a preset temperature. Thus, when the seating surface 311 drives up temperature only when the three-dimensional detection sensor 600 detects a human body, energy efficiency will become high.

The maximum capacity of the toilet seat heater 350 is designed to be 1200 W, for example. Since it raises instantly to a set temperature, the toilet seat heater 350 is driven by the maximum capacity | capacitance until the surface temperature of the toilet seat 300 at least reaches the minimum temperature which does not feel cold uncomfortable when a user sits. This temperature is hereinafter referred to as "cool feeling limit temperature". The feeling of cold threshold temperature was found to be about 29 ° C by subject experiment.

On the other hand, it was found from the test of the subject that the average value of the shortest time required by the user to enter the toilet 300 after changing from the normal wearing state after entering the toilet room was 6 seconds. Therefore, what is necessary is just to set the time to start driving of the toilet seat heater 350, and to reach cooling sense | limit temperature (29 degreeC) shorter than the time until a user removes and sits. Accordingly, the user does not feel cold when sitting on the toilet seat 300.

When the user seats on the toilet seat 300 heated above the cold feeling limit temperature, the seating sensor 202 detects the seated human body and transmits a detection signal to the control unit. Thereby, operation of the washing | cleaning function and drying function which can be used in a seated state is attained.

For example, when the user operates the buttock cleaning switch (not shown) of the remote controller 500, the buttock cleaning nozzle of the cleaning nozzle 201 protrudes forward, and the washing water is ejected to start the butt cleaning. Next, when the end switch (not shown) is operated, the jet of the washing water stops, and the buttock washing nozzle is stored in the original storage position.

Next, when the user operates a drying switch (not shown), the control unit controls the drying unit. Accordingly, warm air is blown out toward the buttocks of the user, and the wet buttocks can be dried by washing.

When the user stands up from the toilet seat 300, the seating sensor 202 detects that the user has left the seat and transmits a detection signal to the controller. By this signal, the control part stops energizing the toilet seat heater 350 after a predetermined time has elapsed.

When the user exits the toilet room, transmission of the human body detection signal of the human body detection sensor 600 is stopped, so that the control unit closes the lid 400 after a predetermined time.

In addition, in the above description, although the structure which used infrared reflection as the non-contact type seating sensor 202 was demonstrated, this invention is not limited to this. When the human body is in close proximity, the electrostatic capacity changes so that a sensor for detecting a seat may be provided on the surface of the main body 200 as the seat sensor 202. Such a sensor is disclosed, for example, in Japanese Patent Laid-Open No. 9-117475.

In addition, in the above description, the toilet seat 300 of the structure which made the upper toilet seat casing 310 the metal, the lower toilet seat casing 320 the resin, and stuck the toilet seat heater 350 inside the upper toilet seat casing 310 is carried out. Explained. However, the present invention is not limited to this. A heat radiating lamp heater may be disposed in the toilet seat 300 in place of the toilet seat heater 350, the upper toilet seat casing 310 may be made of metal or resin, and a radiation heat absorbing layer may be formed inside. The toilet seat of such a structure is disclosed by Unexamined-Japanese-Patent No. 2000-210230, for example. Thus, the structure of the toilet seat heater is not limited.

Also in this case, when the thermal conductivity of the upper toilet seat casing 310 is larger than the thermal conductivity of the lower toilet seat casing 320, it is preferable to adjust the height of the rib 313 provided in the upper toilet seat casing 310. That is, the power consumption is reduced by making the height H3 at the back 312 of the rib 313 provided in the upper toilet seat casing 310 lower than the height H4 of the rib 313 at the seating surface 311. Can be reduced.

In addition, regardless of the material of the upper toilet seat casing 310, when the upper toilet seat casing 310 is selectively heated, the height of the rib 313 on the seating surface 311 is preferably 5 mm or more and 40 mm or less, preferably 15 mm. As mentioned above, 20 mm or less is more preferable. In addition, it is preferable that the upper toilet seat casing 310 protrudes from the lower toilet seat casing 320 in the horizontal direction while the toilet seat 300 is mounted on the toilet. Accordingly, it is possible to prevent the buttocks of the user from contacting the lower toilet seat casing 320 that is not heated.

As described above, the user using the sanitary washing apparatus according to the present invention can easily sit at the optimal position of the seating surface, and can use the sanitary washing apparatus comfortably without impairing the cleaning property. The configuration of the sanitary washing apparatus according to the present invention can also be applied to the use of seating equipment such as furniture.
