With the toilet lid closed, not only the toilet seat but also the sanitary washing device itself is covered with the toilet lid, so that the appearance is clean, the gaps for dust and the like are eliminated, and cleaning properties such as wiping and cleaning are improved. Can be made.
However, when the main body of the sanitary washing device is covered with a toilet lid, there arises a problem of shielding the detection range of the infrared projection human body detection sensor. For this reason, as described in Patent Document 2, it is necessary to expose the human body detection sensor by projecting the human body detection sensor in the lateral direction of the sanitary washing device or by providing a notch at the rear part of the toilet lid. However, if it does in this way, an appearance will worsen and the cleaning property of a sanitary washing device will also fall.

  The present invention has been made on the basis of recognition of such a problem, and includes a sanitary washing device capable of covering substantially the entire sanitary washing device with a toilet lid and capable of reliably detecting a human body. A toilet device is provided.

A toilet lid that is pivotally supported so as to rotate relatively rearward in the main body, and covers substantially the entire upper surface of the toilet seat and the main body in a closed state;
A transmissive window provided at a rear portion of the toilet lid and formed of a material different from the toilet lid;
A human body detection sensor provided on the upper surface of the main body and capable of detecting a human body through the transmission window in a state where the toilet lid is closed;
There is provided a sanitary washing device characterized by comprising:

According to another aspect of the present invention,
A sitting toilet,
The above sanitary washing device;
A toilet device is provided.

  According to the present invention, it is possible to provide a sanitary washing apparatus capable of covering substantially the entire sanitary washing apparatus with a toilet lid and capable of reliably detecting a human body, and a toilet apparatus including the sanitary washing apparatus.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are schematic perspective views of a toilet apparatus equipped with a sanitary washing device according to an embodiment of the present invention.
Moreover, FIG. 3 is the perspective view which looked at the sanitary washing apparatus of this example from the front.

  That is, the sanitary washing device 100 is installed on the Western-style seat toilet 800. The sanitary washing device 100 includes a main body 400, and a toilet seat 200 and a toilet lid 300 that are pivotally supported by the main body 400 so as to be opened and closed. From the main body 400, a water discharge nozzle (not shown) extends into the bowl of the toilet bowl 800 according to the user's switch operation, etc., and water is sprayed from a water discharge port provided near the tip of the user. It is possible to wash the "wet" etc. In the present specification, “water” includes not only cold water but also heated hot water. The main body 400 is appropriately provided with various mechanisms such as a “deodorizing unit”, “warm air unit”, and “room warming unit”, and an exhaust hole 440 and an exhaust hole 450 are appropriately provided on the side surface thereof. Yes. The internal configuration of the main body 400 will be described in detail later.

  The toilet seat 200 is pivotally supported relatively forward in the main body 400, while the toilet lid 300 is pivotally supported relatively rearward in the main body 400. That is, the rotation axis of the toilet seat 200 and the rotation axis of the toilet lid 300 are provided apart in the front-rear direction. In the state where the toilet lid 300 is opened as shown in FIGS. 1 and 3, the main body 400 and the toilet seat 200 are almost completely exposed, and the user can sit on the toilet seat 200 without interfering with the toilet lid 300. it can. Further, the toilet lid 300 can be moved away from the user sitting on the toilet seat 200 by pivotally supporting the toilet lid 300 at the rear portion of the main body 400. As a result, the user sitting on the toilet seat 200 is given a feeling of opening and a comfortable feeling of use is obtained. In addition, for example, even when a thick jacket or a long dress is rolled up and seated on the toilet seat 200, the jacket or dress is less likely to come into contact with the toilet lid 300. There is no hygienic discomfort.

  On the other hand, when the toilet lid 300 is closed as shown in FIG. 2, not only the toilet seat 200 but also the main body 400 is almost completely covered by the toilet lid 300. Thus, if the toilet lid 300 covers almost the entire sanitary washing device, it is very smart, simple and clean. Moreover, by covering the entire sanitary washing device 100 with the toilet lid 300, dust, dust, and the like do not accumulate on the main body 400 as well as the toilet seat 200 when not being used. Furthermore, when the toilet lid 300 is closed, there is no “gap” or “unevenness” on the upper surface of the sanitary washing device 100, so that the entire upper surface of the toilet lid 300 can be smoothed even when wiping with a wet cloth. It can be wiped quickly and the cleanability is improved.

  In the case of this specific example, a stepped portion 405 (see also FIG. 5) is formed on the side surface of the main body 400. When the toilet lid 300 is closed, the stepped portion 405 is aligned in contact with or close to the rear lower end 305 of the toilet lid 300, and the side surface of the main body 400 and the side surface of the toilet lid 300 are substantially the same. Form a surface. As a result, when the toilet lid 300 is closed, a continuous flat surface from the toilet lid 300 to the main body 400 is also formed on the side surface of the sanitary washing device 100, and the appearance is neat and dust and dirt accumulate. Can also be prevented. In addition, even when the side surface of the sanitary washing device 100 is wiped and cleaned with the toilet lid 300 closed, it can be wiped smoothly without being caught by a rag.

And the main-body part 400 of the sanitary washing apparatus of this embodiment has the upper surface used as the surface substantially parallel to the toilet cover 300 of the closed state between the shaft support part of the toilet seat 200, and the shaft support part of the toilet lid 300. FIG. The human body detection sensor 500 is provided on the upper surface. On the other hand, a transmission window 310 is provided at the rear of the toilet lid 300.
4 to 6 are enlarged perspective views showing a mounting portion of the human body detection sensor 500. FIG. 4 shows a state where the toilet lid 300 is closed, and FIGS. 5 and 6 show a state where the toilet lid 300 is opened.
FIG. 7 is an enlarged perspective view of the shaft support portion viewed from the front in a state where the toilet lid 300 is opened.

  A recessed portion 410 is formed on the upper surface of the main body 400, and the human body detection sensor 500 is provided so that a part thereof is embedded in the recessed portion 410. As will be described in detail later, an infrared detection type sensor can be used as the human body detection sensor 500. For example, when a pyroelectric sensor is used, the presence of the user can be detected with high accuracy. In the case of the pyroelectric sensor, the movement of the heating element within a predetermined detection range in front of the pyroelectric sensor can be detected.

  In the state where the toilet lid 300 is closed as shown in FIG. 4, the human body detection sensor 500 detects the presence of the user in front of the sanitary washing device through the transmission window 310. That is, the transmission window 310 transmits infrared rays detected by the human body detection sensor 500. For example, when a pyroelectric sensor is used as the human body detection sensor 500, far infrared rays having a wavelength of about 10 micrometers are detected. Accordingly, the transmission window 310 is made of a material having a certain degree of transmittance with respect to infrared rays in this wavelength band. By using, for example, polyethylene as the material of the transmission window 310, the approach and presence of the user can be detected through the transmission window 310 with high sensitivity even when the toilet lid 300 is closed.

  On the other hand, the toilet lid 300 that supports the transmission window 310 can be formed of a material having a transmittance lower than that of the transmission window 310 for infrared rays. If the toilet lid 300 is made of a material that is harder and stronger than the transmission window 310, there is little deflection and deformation, and scratches are less likely to occur. Further, the color of the toilet lid 300 can be freely selected, and it is easy to match the color of the toilet bowl 800 and the main body 400. Examples of the material of the toilet lid 300 that satisfies these requirements include polypropylene.

  When the human body detection sensor 500 detects a user with the toilet lid 300 closed, the toilet lid 300 can be automatically opened by operating an electric opening / closing unit incorporated in the main body 400, for example. In addition, for example, the toilet seat 200 is heated quickly, the indoor heating unit provided in the main body 400 is operated to warm the toilet, or a small amount of washing water is poured into the toilet bowl 800 in advance to wet the bowl. It is possible to execute processing for suppressing the above.

  When the toilet lid 300 is opened as shown in FIGS. 5 and 6, there is no shielding body in front of the human body detection sensor 500, so that the presence of the user can be detected as it is. The main body 400 is provided with a seating sensor 420 that can detect the presence of a user sitting on the toilet seat 200. As the seating sensor 420, for example, an infrared sensor that emits infrared rays and detects the amount of light reflected by the infrared rays can be used.

FIG. 8 is a schematic view illustrating the structure of the human body detection sensor 500. That is, FIG. 8 shows a structure when a pyroelectric sensor is used as the human body detection sensor 500.
The pyroelectric sensor includes a pyroelectric element 510 mounted on a substrate 530 and a lens 520 disposed to face the light receiving surface. The pyroelectric element 510 uses a pyroelectric material such as PZT (lead zirconate titanate), LiTaO ₃ (lithium tantalate), PbTaO ₃ (lead tantalate), and is divided into a plurality of detection regions. Yes. The lens 520 is also divided into a plurality of lens portions 520L. When a heat source such as a human body moves, the infrared condensing pattern by these lens bodies 520 also moves on the light receiving surface of the pyroelectric element 510, so that the change can be detected.

  FIG. 9 is a partially enlarged longitudinal sectional view of the main body 400 in which the human body detection sensor 500 is embedded.

  In this specific example, as shown in FIG. 9, the human body detection sensor 500 is slightly placed on the upper surface of the main body 400 by bringing the human body detection sensor 500 close to the rear portion of the case cover 430 on the upper surface of the main body 400, i. Protrusively provided. By doing so, the distance between the transmission window 310 and the human body detection sensor 500 can be reduced. As a result, it is possible to detect a wide range while reducing the size of the transmission window 310. That is, when viewed from the human body detection sensor 500, a wide-angle range can be detected through the small transmission window 310.

  As described above, the transmission window 310 needs to be formed of a material having a higher infrared transmittance than the toilet lid 300. For this reason, the toilet lid 300 may have a different color and texture, and has a low hardness. It may be easily deformed or scratched. Even in such a case, according to the present embodiment, the transmission window 310 can be made small and can be provided near the rear end of the toilet lid 300. The effect that it can suppress is acquired.

  Further, as shown in FIG. 9, the body portion 400 is provided with a recessed portion 410, and a portion of the human body detection sensor 500 is embedded in the recessed portion 410, so that the human body detection sensor 500 is attached to the case cover 430 of the body portion. A wide range of angles can be detected without causing a large protrusion from the upper surface. That is, it is possible to reliably detect the human body while maintaining the cleanability of the upper surface of the case cover 430.

  10 and 11 are schematic views illustrating a range in which a human body can be detected by the human body detection sensor 500 in the sanitary washing device 100 of this specific example. 10 shows the detectable range in the horizontal direction and FIG. 11 shows the detectable range in the vertical direction.

  As can be seen from FIG. 10, the human body 900 can be detected by the human body detection sensor 500 within a range of 40 degrees in the horizontal direction. Further, as can be seen from FIG. 11, the human body 900 at the upper front of the sanitary washing device can be detected within a range of 33 degrees in the vertical direction. This is a range sufficient to detect the presence of a user approaching the sanitary washing device 100 or a user standing in front of the sanitary washing device 100 in a normal-sized toilet. Further, as shown in FIG. 11, detection is possible when an adult 900 having a normal height approaches a distance of 2.5 meters from the rear end of the toilet bowl 800. Further, the head when a normal tall adult 900 stands in front of the toilet bowl 800 can also be detected. Further, in general, even in the case of a child 910 whose height is less than 1 meter that can use a toilet alone, detection becomes possible when approaching from the front end of the sanitary washing apparatus 100 to about 100 millimeters. Of course, the head when the child 910 stands in front of the toilet 800 can also be detected. That is, it is possible to reliably detect the presence of a user from an adult to a child who uses the toilet bowl 800 (the sanitary washing device 100).

Next, the transmission window 310 and its mounting structure used in this specific example will be described in more detail.
FIG. 12 is a perspective view showing an attachment part of the toilet lid 300 to which the transmission window 310 is attached.
An opening 340 for attaching the transmission window 310 is formed at the rear end of the toilet lid 300. Thin plate-like rails 350 are provided on the front side wall and the left and right side walls of the opening 340. On the other hand, a support bridge 360 is provided at the rear end of the opening 340. The transmission window 310 passes over the support bridge 360 from the rear side of the toilet lid 300 and is slid and inserted along the rail 350 in the direction of arrow A.

FIG. 13 is a perspective view of the transmissive window 310 as viewed obliquely from above.
FIG. 14 is a perspective view of the transmissive window 310 as viewed obliquely from below.
FIG. 15 is a cross-sectional perspective view of the transmission window 310 cut in the horizontal direction.

  FIG. 16 is an enlarged cross-sectional view showing a cross section of the attachment portion of the transmission window 310.

  Rail grooves 312 that engage with the rail 350 of the toilet lid 300 are provided on the front side surface and the left and right side surfaces of the transmission window 310. As shown by arrow A in FIGS. 12 and 13, the transmission window 310 is slid forward from the rear end of the toilet lid 300 while engaging the rail grooves 312 with the rails 350 on both side ends, thereby opening 340. It can be attached so as to block. When the transmission window 310 is slid to the front end, the rail groove 312 at the front end thereof engages with the rail 350 at the front end of the opening 340. When the transmission window 310 is attached to the toilet lid 300 in this way, the upper surface of the transmission window 310 and the upper surface of the toilet lid 300 are continuous, and there is almost no “step” or “joint” between them. Is done. The appearance is clean, and wiping and cleaning can be performed smoothly.

  12 to 16 show specific examples in which the rail 350 is provided on the side wall of the opening 340 and the rail groove 312 is provided on the side surface of the transmission window 310, but the present invention is not limited to this. For example, on the contrary, a structure in which a rail groove is provided on the side wall of the opening 340 and a rail is provided on the side surface of the transmission window 310 may be employed.

  On the other hand, hooks (engagement convex portions) 314 are provided on both sides of the rear side of the rear portion of the transmission window 310. In this specific example, the hook 314 is formed in a bowl shape, and can be elastically deformed up and down by notching a part of the rail groove 312. On the other hand, as shown in FIG. 12, hook recesses (engagement recesses) 365 are provided at both ends of the support bridge 360 of the toilet lid 300. When the transmission window 310 is slid along the rail 350 to the front end, the hook 314 is engaged with and fixed to the hook recess 365. In this way, the transmission window 310 can be securely and easily attached to the toilet lid 300. When the transmission window 310 attached to the toilet lid 300 is pulled backward with a predetermined force or more, the hook 314 is elastically retracted and the engagement between the hook 314 and the hook recess 365 is released. Accordingly, the transmission window 310 can be slid rearward along the rail 350 and pulled out from the toilet lid 300. Therefore, when the transmission window 310 is damaged or dirty, it is convenient in that it can be easily detached from the toilet lid 300 and replaced, and it is excellent in economy.

  Further, by providing the hook 314 in the vicinity of the rear end of the transmission window 310 as described above, even when the toilet lid 300 is opened as shown in FIG. It can be refreshed.

  FIGS. 12 to 16 show specific examples in which the transmission window 310 is provided with the hook (engagement convex portion) 314 and the support bridge 360 is provided with the hook concave portion (engagement concave portion) 365. Is not limited to this. For example, on the contrary, a structure in which a concave portion for hook (engagement concave portion) is provided in the transmission window 310 and a hook (engagement convex portion) is provided in the support bridge 360 may be employed.

  On the other hand, in this specific example, since the human body detection sensor 500 detects the presence of the user through the transmission window 310 in the state where the toilet lid 300 is closed, the transmission window 310 is configured to transmit infrared rays as easily as possible. It is desirable. Therefore, for example, polyethylene is used as the material of the transmission window 310 as described above. Further, as shown in FIGS. 15 and 16, a thin window portion 320 is provided to increase infrared transmittance, and a thick flange portion 330 is provided around the window portion to support and reinforce.

  When the transmission window 310 is made of high-density polyethylene, if the thickness of the window 320 is reduced to about 0.5 millimeters, sufficient detection sensitivity can be obtained even when a pyroelectric sensor is used as the human body detection sensor 500. On the other hand, if the thickness of the flange portion 330 provided around the window portion 320 is about 1.5 millimeters, the transmissive window 310 can be prevented from being detached or damaged in a normal use mode.

In addition, as described above with reference to FIG. 9, in this specific example, the human body detection sensor 500 protrudes below the transmission window 310, and as shown in FIG. 9, the upper end of the case cover 430, the transmission window 310, The interval S is about 1 millimeter. Therefore, when a pressing force is applied to the transmission window 310 with the toilet lid 300 closed, the window 320 is deformed. However, the deformation amount is limited to 1 millimeter, and the case of a pressing force exceeding that is the case. When the cover 430 receives force, the transmission window 310 can be prevented from being damaged or detached.
Heretofore, the transmission window 310 and its mounting portion in this specific example have been described in detail.

Next, the internal structure of the main body 400 of the toilet device in which the sanitary washing device 100 of this specific example is combined with a direct water pressure toilet will be described in more detail.

The auxiliary operation unit 680 is provided with a switch for operating the “wet” cleaning by the nozzle unit 610. For example, the operation of the sanitary washing device 100 is controlled even when the operation by the remote controller (not shown) is impossible. It is possible. A valve unit 690 is provided at the lower rear portion of the case cover 430. The valve unit 690 has a role of controlling the supply of water supplied from the water supply to the pump unit 650.

  On the other hand, a DC (direct current) controller 700 and a driver unit 710 are provided side by side on the upper front part inside the case cover 430. An electric opening / closing unit 720 and a toilet flushing valve unit 730 are provided at the rear of the case cover 430. The electric opening / closing unit 720 has a role of opening and closing the toilet lid 300. The toilet flushing valve unit 730 has a role of controlling the supply of flush water that flows to the toilet 800. That is, the toilet device of this specific example has a so-called “water direct pressure type” structure, and supplies water supplied from the water supply to the toilet bowl 800 via the toilet flush valve unit 730 without providing a low tank or the like. Perform cleaning.

  On the other hand, a room warming unit 740 is provided at the rearmost part inside the case cover 430. The room warming unit 740 has a role of heating the toilet space in which the toilet apparatus is installed by discharging warm air from the discharge hole 450. In addition, a power cord is disposed at the lower end, and power such as AC 100 volts is supplied from the outside.

FIG. 19 is a perspective view for explaining a mounting structure of the toilet bowl cleaning valve unit 730.
Moreover, FIG. 20 is the schematic diagram which looked at the attachment part of the toilet bowl washing | cleaning valve unit 730 from upper direction.

The toilet flushing valve unit 730 is supported by a toilet base plate 760 fixed to the rear side of the toilet 800 and is connected to the toilet 800 by a water supply pipe 735. A mounting substrate 770 of the main body 400 is fixed on the upper surface of the toilet bowl 800. The toilet flushing valve unit 730 passes through an opening 775 provided in the mounting substrate 770 and projects upward.
FIG. 21 is a perspective view showing an arrangement relationship between the electric opening / closing unit 720 and the toilet bowl cleaning valve unit 730.
FIG. 22 is a schematic view of these elements as viewed from the rear side.
The electric opening / closing unit 720 and the toilet bowl cleaning valve unit 730 are provided at the rear of the main body 400. As described above with reference to FIGS. 17 and 18, each functional unit including the nozzle unit 610 of the sanitary washing device 100 is appropriately disposed below the front portion of the mounting substrate 770 and the electric opening / closing unit 720.

  As described above, the toilet apparatus of this specific example incorporates a plurality of units having various functions.
