Japanese Patent Laid-Open No. 9-135791

  However, while the development of the configuration of the entire warm water flush toilet seat device is progressing to a configuration in which the device body can be made compact and can be installed in various toilet bowl shapes, illumination means and illumination means for displaying the target inside the device body When a dedicated shutter, a driving configuration for opening and closing the shutter, and an air nozzle and an air blowing configuration for cleaning the lens of the illumination means are mounted, there is a problem that the main body itself increases in size and cannot be made compact. . Furthermore, regarding the cleaning of the illumination means, it is difficult to say that the cleaning is appropriately performed only with the above-described configuration. For example, if urine splashes or urine that is not covered by the shutter, urine due to rebounding, stool adherence, etc. dry and stick, it was not possible to clean by blowing alone. There was a need to do.

  The cleaning toilet seat according to the present invention can continuously and clearly display the target display means in a clean state.

  According to a first aspect of the present invention, there is provided a human body washing nozzle for washing a local body part, a toilet seat, target display means for instructing a small target in a toilet bowl on which the toilet seat is placed, and the human body washing nozzle toward the toilet bowl. Driven so as to move forward or backward, the human body washing nozzle and the target display means are provided at a substantially central portion of the toilet seat apparatus main body, and are provided with a shielding means with the same member at the front end facing the inside of the toilet.

  And by providing shielding means, it is possible to prevent sewage splashed from the toilet bowl during stool or directly scattered stool from hitting the target display means, and the target display means can be clearly projected in the long term It becomes. Further, since the shielding means is the same member and also serves as the shielding means for the human body washing nozzle, it is not necessary to provide a complicated mechanism inside the apparatus main body, the number of members is reduced, and the main body can be made compact.

  The second invention is characterized in that when the target display means is displayed, the human body washing nozzle is driven back and forth.

Then, the human body washing nozzle is driven back and forth to release the shielding of the target display means and display the target, so that the human body washing nozzle is not driven except when the target display means is not required, and the dirt is guarded by the shielding means. It becomes possible to do. Since the shielding means is released using the advancing / retreating driving configuration of the human body washing nozzle, it is not necessary to provide a dedicated configuration for driving the shielding means. Further, the human body washing nozzle is driven and moved to a position that does not interfere with target display from the target display means. As a result, the target is displayed only when necessary.

  In the third invention, the target display means is provided above the human body washing nozzle.

  And since the target display means is located above the human body washing nozzle, it becomes a position away from sewage and filth, and it is located at the back of the human body washing nozzle and it is difficult to get dirty, so when displaying the target, Further, the target display means itself is not easily soiled even when target display is not performed.

  According to a fourth aspect of the present invention, a cleaning nozzle for a human body cleaning nozzle is provided, and the target display means is cleaned with cleaning water from the cleaning nozzle.

  At the same time as cleaning the human body washing nozzle, the water for washing the human body washing nozzle also travels to the periphery of the target display means, and the water droplets moisten the surface of the target display means, and the dirt adhering to the surface of the target display means is floated. Since the target display means and the human body washing nozzle are covered with the same shielding means, the shielding means serves as a water channel to the target display means, and at the same time, the cleaning water is surely provided around the target display means. This also encloses the area where the cleaning water is rotated so as to wrap around, so that the cleaning effect for removing dirt from the target display means can be further enhanced.

  According to a fifth aspect of the invention, the target display means has a wall surface around it and is provided in the vicinity of the human body washing nozzle in the toilet seat body, and the advancing / retreating driving direction of the human body washing nozzle and the surrounding wall surface of the target display means are provided in parallel. The wiper means is provided so as to come into contact with at least one surface on the human body washing nozzle side of the wall surface around the target display means.

  And if a human body washing nozzle is driven by this structure, it will become the operation | movement wiped off with the wiper which contact | connected one part to the surrounding wall surface of a target display means. That is, after cleaning the human body washing nozzle, the filth can be removed by driving the human body washing nozzle. It is also effective for removing cleaning water adhering after cleaning performed at the same time as cleaning the human body washing nozzle, and removing adhering dirt. The target display state is not diffused by adhering substances such as water droplets. It becomes possible to project clearly.

  A sixth invention includes a toilet seat toilet lid rotating means having a toilet lid and opening and closing the toilet seat and the toilet lid, and a human body washing nozzle for opening and closing the toilet seat toilet lid rotating means and displaying the target display means It is characterized by interlocking the driving of.

  Thereby, the target display timing, the operation of the toilet lid toilet seat rotating means and the driving timing of the human body washing nozzle are appropriately matched, and the target display can be performed without any trouble in use.

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

(Embodiment 1)
1 is a side view of the toilet seat device, FIG. 2 is a front view, and FIG. 3 is a partially enlarged view of the side view. The toilet seat device includes a toilet seat 2 and a toilet lid 3 which are provided on a toilet seat device body 1 and is installed in a toilet 4. A human body washing nozzle 5 is installed at a substantially central portion of the toilet seat apparatus body 1, and a target means 6 for indicating the inside of the bowl of the toilet 4 is configured near the lower part of the storage position. The cleaning nozzle 5 has a function of cleaning the nozzle itself. The target means 6 has a light source 7 covered with a case 8 and is waterproofed. The case 8 includes a diffusing unit 9 that diffuses a part of the light from the light source 7, and the target display unit 6 is covered with the same member that also serves as a shutter 21 that is a shielding unit for the human body washing nozzle 5. ing. That is, when the human body washing nozzle 5 is in the storage position inside the toilet seat apparatus body, the end of the shutter 21 has a bent portion 21a so as to shield the direction in which the human body washing nozzle 5 and the target display means 6 face the toilet. It is configured. Provided separately from the toilet seat device body 1 to detect the entrance of the user of the toilet seat into the toilet space that can be installed at a position that can detect a person who entered the room earlier according to the installation situation, and a signal from the control unit 10A, a seating detection means 10B on the toilet seat provided in the toilet seat device, and a rotation detection means 7 for detecting the rotation position of the toilet seat 2. Moreover, the control part 12 which controls the target display means 6 based on the signal input from the human body detection means 10A, the seating detection means 10B, and the rotation position detection means 11 is incorporated. In FIG. 2, the toilet seat apparatus main body has a human body drying device 22, and a part of a duct for blowing dry air for drying the human body is branched and blown out in the vicinity of the target display means 6. 22a is provided. 3A shows a state where the human body washing nozzle 5 and the target display means 6 are in the storage position and are shielded by the shutter 21 which is a shielding means, and FIG. 3B shows that the human body washing nozzle 5 is driven forward. The shutter 21 is pushed up to release the shielding so that the light emitted from the target display means 6 is not blocked. B is the driving direction of the human body washing nozzle 5, and C is the human body washing nozzle. , 22a is a cross section of a nozzle cleaning flow path provided above the human body washing nozzle. When cleaning the nozzle, warm water or water is passed through this flow path, and although not shown in the figure, cleaning water is supplied to the tip of the human body washing nozzle 5 where the ejection hole is provided. It is constructed so as to sufficiently clean the vicinity of the front end portion by ejecting from the nozzle.

  With the above configuration, when the user enters the toilet space, the human body detecting means 10A detects the entrance of the human body or the proximity to the apparatus main body, and the toilet seat 2 is in the standing state by the rotational position detecting means 11, and the seating detecting means When the control unit 12 receives a signal indicating that seating is not detected in 10B, the human body washing nozzle 5 is moved forward, the shutter 21 is opened, and the shielding for the target display unit is released. The light source 7 is energized and light is emitted toward the inside of the toilet bowl. At that time, the light is diffused by the diffusing means 9, and a reflected image of the light source 7 softly blurred to a level that is easy to see directly from the user only on the water surface in the toilet bowl is reflected in the area A, which induces urination Add small usage as a target. Since the user is guided to the urination landing position in the reflected image and urinates so as to cancel the reflected image, there is an effect of surely preventing urine scattering. It is most desirable that the target 5 which is a reflected image indicates the approximate center of the water surface in the toilet bowl, but if the urine lands on a position as close to the center as possible to avoid the boundary area between the water surface and the inner surface of the toilet bowl, it will prevent considerable scattering. Since the effect is obtained, the target may be indicated within the range of the water surface.

  If the light source 7 is an LED, it is not a special configuration with directivity. If it is a general-purpose type and has a certain diffusion angle, an LED that is a light source if the diffusion means 9 is configured at a position facing the reservoir surface. It is not necessary for the light emission direction of itself to face the water surface. Therefore, when the LED light emission direction C is provided in parallel with the protruding direction of the human body washing nozzle 5, that is, the forward / backward direction B, the nozzle unit and the installation position of the light source are brought close to each other so It can comprise in a toilet seat apparatus main body. By adopting such a space-saving configuration, the target means 6 can be installed in a small space below the human body washing nozzle 5 that is generally configured in the approximate center of the toilet seat device, so that a target position adjusting means is required. By simply finely adjusting the toilet seat device body 1 back and forth, it is possible to indicate the approximate center of the stored water surface for various toilets with different water surface heights and shapes, and have a target instruction that is inexpensive and has few failures Can be obtained.

Further, the light passing through other than the diffusing means 9 illuminates the inside of the toilet bowl as a whole, and has an effect as a substitute for lighting when the user enters the toilet room without lighting at night. At that time, since the illuminance is lower than the lighting of the toilet room, the illuminance is such that a user who enters the toilet room after waking up does not promote awakening.

  The diffusing means 9 can be obtained by making the inner or outer surface of a transparent resin (for example, acrylic) case 8 semi-transparent by etching or sandblasting. This may be processed into a mold or post-processed into a molded product. When processing the inner surface, since the outer surface can be left as a mirror surface, it is difficult to get dirt such as dirty water, and a bright target can be obtained for a long time without cleaning. On the other hand, when processing to the outer surface, post-processing is easy, and the size of the target can be adjusted by changing the processing size. In addition, by making the case 8 itself translucent (for example, polycarbonate) resin or fluorescent resin, the target means 6 that the whole case 8 shines softly without processing can be realized. In addition, since the shape of the target is changed by changing the shape of the case 8, various targets can be realized.

  It is also conceivable that the diffusing member 9 is formed into a sheet shape and is configured inside the transparent resin case 8. By changing the color and transmittance of the sheet, the brightness and color of the target can be easily adjusted without changing the type of the light source 7. Alternatively, it can be considered that the target means 6 is attached to a hole provided in the lower part of the toilet seat device to irradiate the target. By doing so, the gap of the fitting portion between the target means 6 and the hole at the lower portion of the toilet seat device is protected, so that sewage, feces, tissue waste and the like do not accumulate, and can be kept clean only by simple wiping and cleaning.

  In this way, since the shielding means 21 is the same member and shields the human body washing nozzle as well as the target display means, it is not necessary to provide a complicated mechanism inside the apparatus main body, the number of members is reduced, the space is reduced, and the main body is compact. Can be realized. Since the target display means 6 is normally shielded by the shutter 21 which is a shielding means and is in a shielded state unless the human body washing nozzle is driven, it is possible to prevent contamination.

  Next, the case where the target display means 6 is simultaneously cleaned during the cleaning of the human body cleaning nozzle 5 will be described with reference to FIG. After the target display means 6 displays, when the human body leaves the toilet room and the human body detection means 10A no longer detects the human body, cleaning water is supplied to the nozzle cleaning water channel by the cleaning nozzle 25 for cleaning the human body cleaning nozzle. Water is passed. Then, the shutter 21 which is the shielding means shields the direction desired for the toilet bowl, and the cleaning water is prevented from immediately falling into the toilet bowl, and the washing water 26 flows into the periphery of the target display means 6 and the target display means. The dirt around 6 is washed away. The water cleaned around the human body washing nozzle 5 and the target display means 6 drips into the toilet together with the dirt from the opening at the end of the bent portion 21a of the shutter 21, so there is no problem. Further, this nozzle cleaning operation is always performed even after the human body washing nozzle 5 is used. Similarly, after the stool that does not require the target display means 6, the sewage or the filth scattered during the stool adheres. Can also be cleaned effectively.

  In addition, a groove serving as a flow path is provided on the surface of the shutter 21 that is a shielding unit that faces the human body cleaning nozzle 5 and the target display unit 6 so that the cleaning water passes through the vicinity of the target display unit 6. Alternatively, if a rib through which water is transmitted is provided, it is possible to guide the cleaning water so that the cleaning water can efficiently flow around the target display means 6.

  Furthermore, it has a dry air outlet 22a branched from a dry air duct ejected by the human body drying device 22 for drying the human body, and by drying the water droplets adhering to the periphery of the target display means 6, it is possible to display the target immediately after washing. Even when the means 6 is used, a reflected image can be clearly displayed without being affected by light refraction at the time of target irradiation with water droplets.

In addition, upon receiving a signal from an operation unit provided as a main body sleeve portion or a separate remote controller (not shown) instructing to operate the toilet seat toilet lid rotating means (not shown), the user directly receives the toilet seat 2. Since the toilet seat 2 can be in an upright state without touching and the rotation of the toilet seat is also an operation switch of the target display means 6, a target can be obtained hygienically and easily.

  The human body detection means 10A and the seating detection means 10B are provided separately from the main body and separately provided inside the main body. However, if the human body toilet room entry and seating can be detected by an integrated sensor, It is not limited to the configuration.

  In addition to the means for mechanically detecting the position of the toilet seat 2 as the rotation position detection means 7, use of a toilet seat opening / closing control signal used when the toilet seat 2 is rotated using an electric opening / closing unit, etc. Can be considered.

(Embodiment 2)
FIG. 5 shows a second embodiment of the present invention. FIG. 5 is a partially enlarged view of a side view of the toilet seat apparatus according to Embodiment 2 of the present invention. FIG. 5A shows the human body washing nozzle 5 and the target display means 6 that are shielded by the shielding means 21 and are in the storage position. The state (b) shows a state in which the human body washing nozzle 5 is driven backward when the target display means 5 displays the target. Since the basic configuration of the present embodiment is the same as that of the first embodiment, the same reference numerals are used and description thereof is omitted. The difference is that the target hand display stage 6 is configured in the vicinity of the top of the ejection hole 23 of the cleaning nozzle 5, and the shutter 21 is in a posture to hang down by its own weight, and has no bent portion at the end. The constitution is that the cleaning nozzle 5 is provided with a wiper 24 that comes into contact with the peripheral wall surface 6a of the target display means 6, and the human body cleaning nozzle 5 is driven in parallel to the surface of the wall surface 6a. The normal storage position of the cleaning nozzle 5 is the position shown in FIG. 5A, and when the target display means 6 is displayed, it is driven backward to the position shown in FIG.

  In this embodiment, when the light source 7 of the target display means 6 emits light, the washing nozzle 5 is driven backward to change the position so as not to interfere with the display of the target display means 6. Can be displayed on the screen. The shutter 21 is kept in the shielding state in the hanging position, does not have the bent portion 21a as in the first embodiment, and does not interfere with the display of the target display means 6. And it prevents that sewage, filth, etc. adhere to the human body washing nozzle or the target display means by rebounding.

  When the human body detecting means 10A detects that the human body is absent in the toilet room, the ejection hole 23 of the human body cleaning nozzle 5 operates to the lower side of the target display means 6, and the ejection hole of the cleaning nozzle 25 for cleaning the nozzle. Since the cleaning water can be jetted out to clean the periphery of the human body washing nozzle and the target display means 6, it becomes possible to clean the sewage and filth adhering during urination and defecation. Further, a wiper 24 provided in the nozzle 5 is provided so as to be in contact with a part of the peripheral wall of the target display means, and when the human body washing nozzle 5 is driven backward, water droplets adhering to the target display means 6 are wiped backward. It is possible to leave. As a result, the target is displayed and used by the user, and then the cleaning is performed to remove the dirt. Then, the user immediately enters the toilet room and uses the target means 6. However, the human body cleaning nozzle 5 is driven backwards simultaneously with the target display, and this is also a water droplet removal operation. Therefore, it is affected by the refraction of the irradiation light of the light source due to water droplet adhesion due to undried cleaning water due to continuous use. Absent. Therefore, clear target display can always be performed, and it is possible to save the trouble of cleaning the six stages of the target display hand located around the nozzle which is a fine part.

Further, the operation of the washing nozzle 5 can be linked with the opening operation of the toilet lid by the toilet seat toilet lid rotating means, thereby minimizing the time until the inside of the toilet is illuminated. If there is a closing operation of the toilet seat, it is determined that the seat is used while being seated on the toilet seat, so the target display is stopped. Therefore, the position of the human body washing nozzle is returned to the initial storage position in conjunction with the toilet seat closing operation by the toilet seat toilet lid rotating means. By such an operation, even if it is linked with the human body washing nozzle, there is no deviation in the operation timing, and display and display stop can be performed quickly. Furthermore, even if the driving sound of the human body washing nozzle is generated at the same time as the operation sound of the toilet seat toilet lid rotating means, the timing is the same, so that the user is not uncomfortable.

  In the embodiment of the present application, the human body cleaning nozzle 5 is described as having the target display means 6 positioned above and below the human body cleaning nozzle 5 for one nozzle shape. In the case where a human body washing nozzle having two nozzles is provided, it may be configured to be positioned above and below the approximate center of the two nozzles. In that case, the light from the light source may be irradiated on the water surface in the toilet bowl above the two nozzles and without driving the human body washing nozzle between the two nozzles.

  As described above, the toilet device according to the present invention can obtain a boy's small target with a compact configuration, can reduce the scattering of urine around the urine, and can reduce the generation of bad odor due to urine oxidation / corruption, etc. So it can be used for warm water flush toilet seats. Further, the target irradiation configuration for displaying the landing position on the water surface is not limited to this field and can be used.
