As shown in FIG. 1( a ), the toilet seat 12 is completely covered by the toilet lid 13 in the closed state. Thereby, the aesthetics of the toilet apparatus 100 when not in use can be improved. As shown in FIG.1(b) and FIG.1(c), while having the opening OP in the front, the toilet seat 12 extends rearward and has covered the upper casing 26a.

As shown in Fig. 2, the main body 11 has an upper casing 26a and a lower casing 26b. In addition, as shown in Fig. 3, the main body 11 includes a control unit 20, a solenoid valve 21a, a heater 21b, and a water agent formed in a space surrounded by the upper casing 26a and the lower casing 26b. Rejection 21c, water supply channel 22, radio wave sensor 23, drying fan 24a, drying duct 24b, deodorizing fan 25a, deodorizing duct 25b and nozzle 27 be prepared

In the toilet apparatus 100 shown in FIGS. 1 to 3 , a lower casing 26b is provided inside the toilet 14 . And while each component with which the main-body part 11 is equipped inside this lower casing 26b is arrange|positioned, these components are covered with the upper casing 26a.

The nozzle 27 is provided in the center of the horizontal direction of the toilet seat apparatus 10. The nozzle 27 is configured to move forward and backward with respect to the bowl portion 14a of the toilet bowl 14 . The nozzle 27 can jet the washing water toward the private part of the user seated on the toilet seat 12 in the state advanced to the bowl part 14a.

The electric wave sensor 23 is provided in the position shifted|deviated slightly leftward from the center of the toilet seat apparatus 10. In addition, as shown in FIG. 2, the radio wave sensor 23 is located above the nozzle 27, and is provided so that another member may not be located between the upper casing 26a and the radio wave sensor 23. As shown in FIG.

The radio wave sensor 23 emits radio waves toward the front of the toilet apparatus 100 and detects an object such as a human body that has entered the detection area. In addition, the radio wave sensor 23 can detect the movement (speed, direction, etc.) of an object using the Doppler effect or the like. The radio wave sensor 23 is, for example, a microwave sensor using a microwave frequency band. Since microwaves penetrate materials with relatively low dielectric constant such as wood, resin, and ceramics, the radio wave sensor 23 penetrates the upper casing 26a, the toilet seat 12, and the toilet cover 13 to detect the human body, Also, the movement state (speed) of the human body can be detected.

Also, microwave is one of classification by frequency of radio waves. In general, it refers to radio waves (electromagnetic waves) with a wavelength of 100 µm to 1 m and a frequency of 300 MHz to 3 ㎔. Radio waves in this range include decimeter waves (UHF), centimeter waves (SHF), millimeter waves (EHF), and submillimeter waves.

The control unit 20 controls the operation of each component included in the toilet device 100 . Further, the control unit 20 performs, for example, opening and closing of the toilet lid 13 , heating of the toilet seat 12 , washing of the bowl portion 14a, and the like according to the result of detection of the user by the radio wave sensor 23 .

Here, with reference to FIG. 2 again, the toilet seat apparatus 10 which concerns on this embodiment is demonstrated in detail. The toilet seat 12 has an upper plate 12a and a lower plate 12b. A hollow is formed between the upper plate 12a and the lower plate 12b, and a heating means 12c is formed in this space.

The upper plate 12a and the lower plate 12b extend in the front-rear direction to follow the upper surface of the toilet 14 and the upper surface of the upper casing 26a when the toilet seat 12 is lowered, and are located behind the radio wave sensor 23 It is connected to the formed toilet seat rotation part 28. For this reason, in the state in which the toilet seat 12 went down, the radio wave sensor 23 is covered with the upper board 12a and the lower board 12b. In other words, a part of the upper plate 12a and a part of the lower plate 12b are located obliquely above and directly above the radio wave sensor 23 . Therefore, the radio wave TW radiated from the radio wave sensor 23 penetrates these upper plate 12a and lower plate 12b and spreads forward of the toilet apparatus 100 .

The respective thicknesses of the upper plate 12a and the lower plate 12b are the same in the vicinity of the radio wave sensor 23 (that is, a portion through which the radio wave TW emitted from the radio wave sensor 23 mainly transmits). In other words, in the vicinity of the radio wave sensor 23, the upper surface and the lower surface of the upper plate 12a are parallel, and the upper surface and the lower surface of the lower plate 12b are parallel. More specifically, in a region through which 30% or more of the maximum radio wave intensity among radio waves TW emitted from the radio wave sensor 23 is transmitted, the thicknesses of the upper plate 12a and the lower plate 12b are the same. That is, in the description of the present embodiment, each thickness of the upper plate 12a and the lower plate 12b in the region through which 30% or more of the maximum electric wave intensity is transmitted is the same as the thickness of the portion through which the radio wave TW is transmitted is the same. means the same

The heating means 12c is, for example, an induction heating coil made of metal. When the heating means 12c is an induction heating coil, the upper plate 12a includes, for example, a heating element having high magnetic permeability such as SUS 430. In the example shown in FIG. 2, a plurality of induction heating coils are formed, and each induction heating coil is formed in an annular shape so as to surround the opening OP. When a high-frequency current flows through each induction heating coil, a magnetic field is generated around the induction heating coil. An eddy current flows through the heating element of the upper plate 12a by this magnetic field in a direction opposite to the current flowing through the induction heating coil, and the toilet seat 12 is heated by Joule heat generated by the eddy current.

The radio wave sensor 23 is provided so that at least a part of the radio wave sensor 23 is located above the heating means 12c. That is, at least a part of the position in the vertical direction of the radio wave sensor 23 is higher than the position in the vertical direction of the heating means 12c.

In addition, the radio wave sensor 23 is formed such that at least a portion of the radio wave sensor 23 is positioned above the rear end EP of the opening OP. That is, at least a part of the position in the vertical direction of the radio wave sensor 23 is higher than the position in the vertical direction of the rear end EP.

The toilet lid 13 has an upper plate 13a and a lower plate 13b. A hollow is formed between the upper plate 13a and the lower plate 13b. The lower plate 13b has a window portion 13c, and a light source unit 13d is provided adjacent to the window portion 13c. The window portion 13c is configured to transmit ultraviolet light, and is formed so as to be positioned above the bowl portion 14a with the toilet lid 13 closed. When the toilet lid 13 is closed, ultraviolet rays are irradiated from the light source unit 13d to the bowl 14a to sterilize the bowl 14a.

The respective thicknesses of the upper plate 13a and the lower plate 13b are the same in the vicinity of the radio wave sensor 23 . In other words, in the vicinity of the radio wave sensor 23, the upper surface and the lower surface of the upper plate 13a are parallel, and the upper surface and the lower surface of the lower plate 13b are parallel.

The radio wave sensor 23 is provided so that at least a part of the radio wave sensor 23 is located above the light source unit 13d. That is, at least a part of the position in the vertical direction of the radio wave sensor 23 is higher than the position in the vertical direction of the light source unit 13d.

The electric wave radiated from the electric wave sensor 23 passes above the heating means 12c of the toilet seat 12, the rear end EP of the opening OP, and the light source unit 13d of the toilet lid 13, and the toilet seat apparatus It proceeds toward the front of (10). That is, the position and direction of the radio wave sensor 23 are adjusted so that the radio wave radiated from the radio wave sensor 23 passes above the components thereof.

Here, in order to demonstrate the action|action and effect by this embodiment, the subject which another toilet seat apparatus has is described using FIG.

It is sectional drawing which shows the toilet seat apparatus by a reference example.

In the toilet seat apparatus shown in FIG. 4, the toilet seat rotation part 28 is formed in front of the electric wave sensor 23, and the rear end part of the toilet seat 12 is located in front of the electric wave sensor 23. As shown in FIG. In the case of this toilet seat device, a part of the radio wave TW radiated toward the front of the electric wave sensor 23 is incident on the rear end of the toilet seat 12 , and the other part propagates without incident on the toilet seat 12 . At this time, the radio wave TW incident on the rear end of the toilet seat 12 is refracted at the interface between the toilet seat 12 and air.

The rear end of the toilet seat 12 is bent and its thickness is changed. Moreover, the refractive index of resin etc. which comprises the toilet seat 12 is higher than the refractive index of air. For this reason, as shown in FIG. 4, a part of radio wave TW advances diagonally upward of the radio wave sensor 23, and another part advances diagonally downward of the radio wave sensor 23. As shown in FIG. As a result, a region with a small radio wave intensity is generated in front of the radio wave sensor 23 because it is difficult to radiate the radio wave. When the intensity of the electric wave in front of the radio wave sensor 23 is small, the intensity of the reflected wave from the human body decreases, and the possibility that the radio wave sensor 23 cannot accurately detect the user of the toilet apparatus increases.

On the other hand, in the case of the toilet seat apparatus 10 which concerns on this embodiment, the toilet seat 12 covers the electric wave sensor 23, and the rear end is located behind the electric wave sensor 23. As shown in FIG. For this reason, the radio wave TW radiated|emitted from the radio wave sensor 23 does not pass through the curved rear end part, but travels forward of the radio wave sensor 23. As shown in FIG. That is, according to this embodiment, it becomes possible to suppress the fall of the electric wave intensity|strength in the front of the radio wave sensor 23, and to detect the to-be-detected target, such as a user of a toilet apparatus, with high precision.

In addition, in this embodiment, the thickness of the toilet seat 12 is the same in the vicinity of the electric wave sensor 23. As shown in FIG. Specifically, the respective thicknesses of the upper plate 12a and the lower plate 12b constituting the toilet seat 12 are the same in the vicinity of the radio wave sensor 23 . Here, assuming that the toilet seat 12 is made of resin, the electric wave TW radiated from the radio wave sensor 23 is the amount of resin with respect to air when incident on the lower surfaces of the upper plate 12a and the lower plate 12b, respectively. It is refracted according to the refractive index, and is refracted according to the refractive index of air with respect to the resin when it is incident on each upper surface. At this time, if the thicknesses of the upper plate 12a and the lower plate 12b are the same, the angle of incidence when incident on each lower surface is equal to the angle of refraction when incident on each upper surface. That is, it becomes possible to suppress the change in the propagation direction of radio waves before and after the incident to the upper plate 12a and the lower plate 12b.

For this reason, by making the thickness of the toilet seat 12 the same in the vicinity of the electric wave sensor 23, the fall of the electric wave intensity in front of the electric wave sensor 23 is further suppressed, and the to-be-detected target of a user of a toilet apparatus etc. can be detected with higher precision.

When the toilet seat device 10 includes the toilet seat cover 13 , the thickness of the upper plate 13a and the lower plate 13b of the toilet seat lid 13 is the same in the vicinity of the radio wave sensor 23 as in the toilet seat 12 . it is preferable By employing such a configuration, it is possible to suppress a change in the propagation direction of the electric wave TW caused by the toilet lid 13 .

In addition, the rear end EP of the opening OP is curved, and since the propagation direction of the radio wave TW is changed when the radio wave TW is incident, the radio wave sensor 23 indicates that the radio wave TW passes the rear end EP. It is preferable to radiate the radio wave TW so as not to transmit it. At this time, it becomes possible to radiate|radiate an electric wave from the electric wave sensor 23 toward the downward direction by providing the radio wave sensor 23 above the rear-end part EP. In this way, it becomes possible to detect a short child, an elderly person, etc. with high precision.

Similarly, the radio wave sensor 23 preferably radiates the radio wave TW so that the radio wave TW does not pass through the heating means 12c including the metal. This is because the metal has a low dielectric constant and thus it is difficult to transmit radio waves (TW). By providing the electric wave sensor 23 above the heating means 12c, it becomes possible to radiate|radiate an electric wave from the electric wave sensor 23 downward more. In this way, it becomes possible to detect a short child, an elderly person, etc. with high precision.

Similarly, it is preferable that the radio wave sensor 23 emits the radio wave TW so that the radio wave TW does not pass through the light source unit 13d when the toilet lid 13 is closed. This is because the electrode, the light emitting part, etc. included in the light source unit 13d contain metal, and the radio wave TW is hardly transmitted. By providing the radio wave sensor 23 above the light source unit 13d, it becomes possible to radiate an electric wave from the radio wave sensor 23 further downward. In this way, it becomes possible to detect a short child, an elderly person, etc. with high precision.

Moreover, when the toilet seat 12 goes up because the toilet seat rotation part 28 is provided behind the electric wave sensor 23, it will be in the state in which the toilet seat 12 does not exist in front of the electric wave sensor 23. For this reason, the refraction and attenuation of the electric wave TW by the toilet seat 12 in the state in which the toilet seat 12 was raised are suppressed, and it becomes possible to detect a detection target more precisely.

(1st modification)

It is sectional drawing which expanded the toilet seat apparatus vicinity of the toilet apparatus by the 1st modification of embodiment.

The toilet seat apparatus by embodiment may have the structure of the toilet seat shown in FIG. 5 instead of the structure of the toilet seat shown in FIG. That is, in the toilet seat apparatus 10 shown in FIG. 2, the electric wave TW radiated|emitted from the radio wave sensor 23 penetrates the upper plate 12a and the lower plate 12b, and propagates to the front of the toilet seat apparatus 10. As shown in FIG. On the other hand, in the toilet seat apparatus 10a shown in Fig. 5, the upper plate 12a and the lower plate 12b are provided around the opening OP of the toilet seat 12, but the lower plate 12b is the upper plate ( 12a) so that only the upper plate 12a extends rearward. For this reason, the radio wave TW radiated|emitted from the radio wave sensor 23 penetrates only the upper board 12a, and advances to the front of the toilet seat apparatus 10. As shown in FIG.

Also in the toilet seat apparatus according to the present modification, since the thickness of the upper plate 12a is the same in the vicinity of the electric wave sensor 23, it becomes possible to radiate the electric wave TW in the forward direction of the electric wave sensor 23 substantially equally, and the toilet apparatus It becomes possible to detect a detection target, such as a user, with high precision.

(Second Modification)

It is sectional drawing which expanded the toilet seat apparatus vicinity of the toilet apparatus by the 2nd modified example of embodiment.

The toilet seat device 10b according to the second modification shown in FIG. 6 includes a toilet seat reinforcement part 12d, a toilet seat reinforcement part 12e, and a toilet seat cover reinforcement part 13e with respect to the toilet seat device 10 shown in FIG. be prepared

The toilet seat reinforcement parts 12d and 12e are formed in the upper surface of the lower plate 12b in the back of the toilet seat 12. As shown in FIG. That is, the toilet seat reinforcement part 12d and the toilet seat reinforcement part 12e are formed in the inside of the toilet seat 12, and are located between the upper plate 12a and the lower plate 12b.

More specifically, the toilet seat reinforcement part 12d is formed in the inside of the toilet seat 12 in front of the electric wave sensor 23. As shown in FIG. The position in the vertical direction of at least one part of the toilet seat reinforcement part 12d is the same as the position in the vertical direction of at least one part of the electric wave sensor 23, for example. The toilet seat reinforcement part 12e is formed in the inside of the toilet seat 12 above the electric wave sensor 23. As shown in FIG.

The toilet seat reinforcement parts 12d and 12e are several projections comprised with resin, for example, and are formed integrally with the lower plate 12b. In addition, the toilet seat reinforcement parts 12d and 12e are formed continuously from the left edge part inside the toilet seat 12 to the right edge part, for example.

The radio wave TW is radiated through the area between the toilet seat reinforcement parts 12d and 12e. In other words, the toilet seat reinforcing parts 12d and 12e are not formed in the range where the electric wave TW is substantially radiated so that the thickness of the toilet seat 12 of the part through which the electric wave TW transmits is the same. In this way, even when the toilet seat reinforcement parts 12d and 12e are provided, a decrease in the electric wave intensity in front of the electric wave sensor 23 is suppressed, and it becomes possible to detect a detection target such as a user of the toilet device with high accuracy. . In addition, the range in which the radio wave TW is substantially radiated is a region in which 30% or more of the maximum radio wave intensity is radiated, as described above.

When the toilet seat pivoting part 28 is formed behind the electric wave sensor 23, compared with the case where the toilet seat pivoting part 28 is formed in front of the electric wave sensor 23, the rear end of the opening OP and a toilet seat turn The distance between the east side 28 is increased. That is, the distance between the parts supporting the upper plate 12a from below becomes long. For this reason, when the user of the toilet apparatus 100 is seated on the toilet seat 12, the force applied to the upper plate 12a becomes large. If the force applied to the upper plate 12a increases, there is a possibility that the upper plate 12a is damaged.

In the toilet seat apparatus 10b by this modification, the toilet seat reinforcement part 12d is formed in the toilet seat 12 inside. By forming the toilet seat reinforcing portion 12d, even when the upper plate 12a is deformed during seating, the toilet seat reinforcing portion 12d supports the upper plate 12a from below to suppress excessive deformation of the upper plate 12a. Therefore, according to this modification, in order to raise the detection precision of the radio wave sensor 23, even when the toilet seat 12 is lengthened in the front-back direction, the possibility that the damage|damage of the toilet seat 12 generate|occur|produces can be reduced.

Further, if the toilet seat reinforcing portion 12d is in contact with the top plate 12a, when the user sits on the toilet seat 12, a large force is applied to the toilet seat reinforcing portion 12d, and there is a possibility that the toilet seat reinforcing portion 12d may be damaged. For this reason, it is preferable that the toilet seat reinforcement part 12d is spaced apart from the upper board 12a in an up-down direction, and is formed. According to this structure, when the upper plate 12a is deformed while supporting the weight of the user in the upper plate 12a, the upper plate 12a is supported from below by the toilet seat reinforcing part 12d, and excessive deformation of the upper plate 12a is prevented. can be suppressed In addition, it is preferable that the toilet seat reinforcement part 12d is formed so that it may not contact the heating means 12c when the upper plate 12a deform|transforms downward.

Moreover, when the toilet seat rotation part 28 is formed behind the radio wave sensor 23 and the length in the front-back direction of the toilet seat 12 becomes long, the force required in order to rotate the toilet seat 12 becomes large, and the toilet seat 12 A large force is applied to the vicinity of the toilet seat rotating part 28 of When a large force is locally applied to the toilet seat 12 , the toilet seat 12 may be damaged. Moreover, deformation may generate|occur|produce in the toilet seat rotation part 28 vicinity of the toilet seat 12 at the time of rotation, and the rotation operation of the toilet seat 12 may become unstable.

On the other hand, in the toilet seat apparatus 10b by this modified example, the toilet seat reinforcement part 12e is formed in the inside of the toilet seat 12 above the electric wave sensor 23. By forming the toilet seat reinforcement part 12e, the intensity|strength of the part to which a force is applied at the time of rotation can be raised, while reducing the possibility that the toilet seat 12 may be damaged, the rotational operation of the toilet seat 12 can be more stable. Therefore, the case where a toilet seat is incorrectly detected as a human body is suppressed, and the performance of a radio wave sensor is also stabilized.

Further, in the portion where the toilet seat reinforcing portion 12e is formed, the force applied at the time of seating is smaller than the portion in which the toilet seat reinforcing portion 12d is formed. For this reason, in order to raise the intensity|strength of the toilet seat rotation part 28 vicinity of the toilet seat 12 effectively, it is preferable that the toilet seat reinforcement part 12e contact|connects the upper board 12a, and is formed.

The rear end of the toilet lid reinforcing part 13e is connected to the toilet lid rotating part 29, and the side and front ends are connected to the lower plate 13b. For this reason, when the toilet lid 13 is rotated, a force is transmitted from the toilet lid pivoting portion 29 to the toilet lid 13 via the toilet lid reinforcing portion 13e to rotate the toilet lid 13 . In the example shown in FIG. 6 , the toilet lid reinforcing part 13e and the toilet lid rotating part 29 are integrally formed to connect the parts having respective functions, but these members may be formed separately and connected to each other.

The toilet lid reinforcing part 13e is formed in the center of the back of the toilet lid 13 as shown, for example in FIG.1(b). Further, as shown in FIG. 6 , the toilet lid reinforcing portion 13e extends forward when the toilet lid 13 is closed, and extends from the toilet lid pivoting portion 29 above the radio wave sensor 23 . has been The toilet lid reinforcing portion 13e together with, for example, the lower plate 13b constitutes a part of the lower surface of the toilet lid 13 . Alternatively, the toilet lid reinforcing part 13e may be formed inside the toilet lid 13 and connected to at least one of the upper plate 13a and the lower plate 13b.

The thickness of the toilet cover reinforcing part 13e is greater than the thickness of the lower plate 13b. The toilet lid reinforcing portion 13e is made of a material having higher strength than the toilet lid 13 (upper plate 13a and lower plate 13b) such as metal (eg, SUS304).

As for the toilet lid 13, similarly to the toilet seat 12, since the toilet lid pivoting portion 29 is formed behind the radio wave sensor 23, the toilet lid 13 is rotated by the toilet lid pivoting portion 29. At this time, a large force is applied to the vicinity of the toilet lid pivoting portion 29 of the toilet lid 13 . If a large force is applied locally to the toilet lid 13 , there is a possibility that the toilet lid 13 may be damaged.

In the toilet seat apparatus 10b according to the present modification, the toilet lid reinforcing portion 13e is formed, and the toilet lid 13 is rotated by the toilet lid pivoting portion 29 via the toilet lid reinforcing portion 13e. all. As described above, the toilet lid reinforcing part 13e has a higher strength than the toilet lid 13 . For this reason, compared to the case where the toilet lid 13 is directly rotated by the toilet lid pivoting portion 29, the force applied to the toilet lid 13 is reduced, thereby reducing the possibility of the toilet lid 13 being damaged. . In addition, the toilet lid reinforcing part 13e is formed over the electric wave sensor 23 from the toilet lid pivoting part 29 to increase the area of the connecting portion between the toilet lid 13 and the toilet lid reinforcing part 13e. Consists of. According to this structure, when the toilet lid 13 is rotated, the force applied to the connection portion between the toilet lid 13 and the toilet lid reinforcing part 13e is further reduced, thereby reducing the possibility of damage to the toilet lid 13 . can be further reduced. In addition, erroneous detection of the toilet lid as a human body is suppressed, and the performance of the radio wave sensor is also stabilized.
