FIG. 2 is a front view of the cabinet in FIG. 1 as seen from the front.
FIG. 3 is a perspective view showing the cabinet alone.
As shown in FIGS. 2 and 3, the cabinet 100 includes a cabinet body 10 and a radio wave sensor 20. As shown in FIGS. Moreover, in this example, the cabinet 100 further includes an illumination section 30 , a control section 40 , a washing machine 50 , and a paper winding machine 60 . The cabinet is not limited to one equipped with the washbasin 50 and the paper-roller 60. For example, a box such as a lining whose top surface is used as a luggage rack, or a pipe line, a tank, etc. are arranged inside. It also contains the body. That is, the cabinet according to this embodiment is a box-shaped body installed on the walls RW, LW, FW, BW and the floor surface FS of the toilet room TR.

The cabinet body 10 is formed in the shape of a substantially rectangular parallelepiped box having a storage portion 11 capable of storing articles therein. In this example, the cabinet body 10 extends forward from the toilet bowl 210 . In other words, the front end of the cabinet body 10 is positioned forward of the front end 210a of the toilet bowl 210 . Note that the front end of the cabinet body 10 may be located behind the front end 210a of the toilet bowl 210 . In addition, the storage unit 11 is not limited to a box-like one, and one or more of the side plate, the rear plate, the bottom plate, the top plate, and the front plate may be omitted. .

The cabinet body 10 is attached, for example, to the right side wall RW or the left side wall LW of the toilet room TR. In this example, the cabinet body 10 is attached at a position away from the floor surface FS of the toilet room TR. In other words, in this example, a space is formed between the cabinet body 10 and the floor surface FS. The cabinet body 10 is a so-called half cabinet. The cabinet body 10 may be placed, for example, on the floor surface FS of the toilet room TR.

Also, in this example, the cabinet body 10 extends to the wall BW on the rear side. In other words, the rear end of the cabinet body 10 is in contact with the wall BW on the rear side. The rear end of the cabinet body 10 may be positioned forward of the rear wall BW or rearward of the rear wall BW. That is, the cabinet body 10 may be separated from the rear wall BW, or may be embedded in the rear wall BW.

The storage portion 11 has a first portion 11a accessible to the user and a second portion 11b not accessible to the user. In other words, the first portion 11a is a portion from which the user can take in and out items such as toilet paper and cleaning tools, and the second portion 11b is a portion from which the user cannot take in and take out items.

The first portion 11a has, for example, an openable/closable door DR on the toilet bowl 210 side surface. In this example, the door DR is substantially parallel to the right side wall RW or the left side wall LW of the toilet room TR, and substantially perpendicular to the floor surface FS of the toilet room TR. The door DR may be inclined with respect to the right side wall RW, the left side wall LW, and the floor surface FS of the toilet room TR.

The door DR is, for example, a push type door without a handle, and the user can open the door DR by pushing the door DR. In this example, a cigarette holder 60 is provided in the center of the cabinet body 10 in the front-rear direction, and two doors DR are provided in front of the cigarette holder 60 and one door DR is provided behind the cigarette holder 60 . In other words, in this example, two first portions 11a are provided at the front of the paper winding device 60 and one at the rear of the paper winding device 60 .

The second portion 11b is provided behind the first portion 11a positioned behind the cigarette holder 60. As shown in FIG. In other words, the second portion 11 b is provided at the rearmost portion of the storage portion 11 . The second portion 11b is located behind the front end 210a of the toilet bowl 210, for example. The second portion 11b has, for example, a side plate provided so as to cover the surface on the toilet bowl 210 side. In other words, the surface of the second portion 11b on the toilet bowl 210 side is closed by the side plate. For convenience of explanation, FIG. 3 omits a side plate provided on the surface of the second portion 11b on the toilet bowl 210 side. The second portion 11b is provided as necessary and can be omitted. That is, the storage portion 11 does not have to have the second portion 11b.

The radio wave sensor 20 is provided in the housing portion 11 of the cabinet body 10 . The radio wave sensor 20 constitutes the sensor of the present invention, and is positioned above the toilet lid 230 when the toilet lid 230 of the toilet device 200 is in the fully closed position. The radio wave sensor 20 detects a human body in the toilet room TR. The radio wave sensor 20 is, for example, a microwave sensor. Instead of the radio wave sensor 20, for example, an infrared light projecting/receiving distance measuring sensor, a pyroelectric sensor, or the like may be used.

In the embodiment, radio waves emitted from the radio wave sensor 20 can pass through the cabinet body 10 . In other words, the wall of the cabinet body 10 is made of a material that allows the radio waves emitted from the radio wave sensor 20 to pass therethrough.

The radio wave sensor 20 is provided inside the first portion 11 a or the second portion 11 b of the storage portion 11 . The radio wave sensor 20 is provided, for example, in the storage section 11 positioned behind the front end 210a of the toilet bowl 210 . The radio wave sensor 20 is preferably provided on the wall BW side located behind the toilet device 200 (toilet bowl 210). In other words, the radio wave sensor 20 is preferably provided on the rear side of the toilet device 200 (on the fulcrum side of the toilet lid 230).

As a result, the principal axis A1 of the radio wave sensor 20 can be directed toward the front of the toilet device 200 to emit light. As a result, the moving direction of the human body (user) toward the toilet device 200 and the radiation direction of radio waves from the radio wave sensor 20 can be made the same as much as possible, so that the human body can be detected efficiently. can.

In this example, the radio wave sensor 20 is provided inside the second portion 11b on the wall BW side. In this way, by providing the radio wave sensor 20 in the second portion 11b inaccessible to the user, it is possible to prevent the user from changing the mounting angle of the radio wave sensor 20 by mistake. As a result, it is possible to suppress deterioration in the detection accuracy of the human body in the toilet room TR due to a change in the mounting angle of the radio wave sensor 20 or the like.

FIG. 4 is a plan view showing the main axis output from the radio wave sensor.
FIG. 5 is a perspective view showing a state in which the main shaft of the sensor passes above the toilet lid when the toilet lid is fully closed.
FIG. 6 is a perspective view showing a state where the main shaft of the radio wave sensor interferes with the toilet lid when the toilet lid begins to open.
FIG. 7 is a perspective view showing a state in which the main axis of the radio wave sensor passes above the toilet seat when the toilet lid is fully open.

The radio wave sensor 20 detects a human body entering the toilet room TR and a human body leaving the toilet room TR. Also, the radio wave sensor 20 detects a human sitting on the toilet seat 220 . That is, as shown in FIG. 7, the main axis A1 of the radio wave sensor 20 passes above the toilet seat 220 when the toilet lid 230 is in the fully open position. The main axis A1 of the radio wave sensor 20 is the maximum directivity direction in which the strength of the radio waves in the detection area of the radio wave sensor 20 is maximized.

Furthermore, the radio wave sensor 20 is arranged so that the main axis A1 passes between the fully closed position (position shown in FIG. 5) and the fully opened position (position shown in FIG. 7) of the toilet lid 230 . That is, the radio wave sensor 20 is positioned and oriented such that the toilet lid 230 during the opening operation intersects the main axis A1 of the projected radio wave. The radio wave sensor 20 is positioned above the toilet lid 230 when the toilet lid 230 is in the fully closed position. It is sufficient that the main axis A1 of the toilet 20 passes above the toilet lid 230, and the radio wave sensor 20 may be provided below the toilet lid 230 in the fully closed position.

For example, when the radio wave sensor 20 is arranged behind the toilet bowl 210, the principal axis A1 of the radio wave sensor 20 always overlaps the open toilet lid 230 when the toilet lid 230 is in the fully open position. Therefore, radio waves are attenuated by the toilet lid 230, and there is a concern that the human body detection state may become unstable. Therefore, the radio wave sensors 20 are arranged in the cabinet main body 10 on the left and right sides and in front of the toilet bowl 210 . Thereby, the main axis A1 of the radio wave sensor 20 extends from the side of the toilet lid 230 along the upper surface of the toilet lid 230 when the toilet lid 230 is in the fully closed position. Thereby, the radio wave sensor 20 quickly detects the opening of the toilet lid 230 from the fully closed position.

In this case, the radio wave sensor 20 detects the toilet lid 230 when the angle (opening angle) of the toilet lid 230 with respect to the horizontal direction is 70 degrees or less, for example. As a result, the radio wave sensor 20 detects the open state of the toilet lid 230 even if a user enters the toilet room TR from a blind spot in the detection area, or if a human body cannot be detected due to noise or the like. Entry of a human body into the toilet room TR can be indirectly detected quickly.

As shown by the dashed line in FIG. 4, the main axis A1 of the radio wave sensor 20 is positioned above the toilet lid 230 so that the distance L1 passing through the front side of the central portion X of the toilet lid 230 in the front-rear direction is behind the central portion X. It is longer than the distance L2 passing through the side. As shown in FIG. 2, the central portion X of the toilet lid 230 in the front-rear direction is positioned at half the length B from the front end of the toilet lid 230 to the rear end of the pivot shaft.

Here, as shown in FIG. 6, when the toilet lid 230 is opened, the movement of the toilet lid 230 per unit time is greater on the front end side of the toilet lid 230 than on the rotating shaft side (rear end side) of the toilet lid 230 . Large quantity. Therefore, by making the distance L1 longer than the distance L2 as in this configuration, the radio wave sensor 20 can detect the movement of the toilet lid 230 more reliably and quickly. That is, the radio wave sensor 20 can detect the toilet lid 230 immediately after the toilet lid 230 starts to open, and can detect the entry of the human body into the toilet room TR as quickly as possible. The main axis A1 of the radio wave sensor 20 preferably passes at least above the toilet lid 230 and forward of the central portion X of the toilet lid 230 in the front-rear direction, even if it does not pass behind the central portion X. good.

The lighting section 30 is provided in the lower portion of the cabinet body 10 . The illumination unit 30 illuminates the interior of the toilet room TR. The lighting unit 30 constitutes equipment provided in the toilet room TR of the present invention, and irradiates light downward of the cabinet body 10 . Thereby, the illumination unit 30 can illuminate the floor surface FS and bring about a presentation effect of light in the toilet room TR. In this example, the lighting unit 30 is provided in the center of the cabinet body 10 in the front-rear direction, and is positioned below the cigarette holder 60 .

The position where the lighting unit 30 is provided is not limited to this. The lighting unit 30 may be provided, for example, in the upper part of the cabinet body 10 . By providing the illumination unit 30 in the upper part of the cabinet body 10, the top plate (counter) of the cabinet body 10 can be illuminated. Also, the illumination unit 30 may be provided under the washbasin 50, for example. By providing the illumination part 30 under the wash basin 50, the surroundings of the wash basin 50 can be illuminated. A light source of the illumination unit 30 is, for example, an LED (light emitting diode). The light source of the illumination unit 30 is not limited to LEDs, and may be any light source capable of emitting visible light.

The control section 40 is provided in the storage section 11 of the cabinet body 10 . The control unit 40 has an input side connected to the radio wave sensor 20 and an output side connected to the lighting unit 30 . The control unit 40 controls the operation of the lighting unit 30 based on the detection results transmitted from the radio wave sensor 20 . In other words, the control unit 40 transmits a control signal for controlling the operation of the lighting unit 30 to the lighting unit 30 .

In this example, control unit 40 is provided separately from radio wave sensor 20 , but control unit 40 may be provided inside radio wave sensor 20 and lighting unit 30 . Note that the control unit 40 may bidirectionally communicate with the radio wave sensor 20 and the lighting unit 30 .

When the radio wave sensor 20 detects that the human body has entered the toilet room TR, the control unit 40 operates (turns on) the lighting unit 30 . Further, when the radio wave sensor 20 detects that the human body has left the toilet room TR, the control section 40 turns off the lighting section 30 . At this time, when the radio wave sensor 20 detects the leaving of the room, the control unit 40 may immediately turn off the lighting unit 30. Alternatively, the control unit 40 may set a delay time (for example, 90 seconds) so that the lighting unit 30 turns off after the delay time. may be turned off.

Furthermore, even if the radio wave sensor 20 does not detect a human body, the control unit 40 operates (turns on) the lighting unit 30 when the toilet lid 230 is detected. Specifically, when the human body detection sensor 215 provided in the toilet device 200 detects a human body, the toilet lid 230 starts to open from the fully closed position. The radio wave sensor 20 indirectly detects the entry of the human body into the toilet room TR by detecting the toilet lid 230 that has begun to open. Then, the control unit 40 turns on the lighting unit 30 . As a result, the interlocking between the opening of the toilet lid 230 and the lighting of the lighting unit 30 can be improved.

Cabinet 100 may further include an operation unit (for example, a switch, a remote controller, etc.) for operating lighting unit 30 . In addition to the control based on the detection result of the radio wave sensor 20, the control unit 40 may control the operation of the lighting unit 30, for example, based on the operation of the operation unit by the user.

By providing the illumination unit 30 and the control unit 40 in this manner, the illumination unit 30 can be controlled by the control unit 40 based on the detection result of the radio wave sensor 20 in the cabinet 100 . Therefore, without using a dedicated toilet device, the interior of the toilet room TR can be provided with a lighting effect.

In addition to detecting the human body, the radio wave sensor 20 also detects the toilet lid 230, so regardless of the layout of the toilet room TR, the user's entry into the toilet room TR, opening of the toilet lid 230, In addition, interlocking of lighting of the illumination unit 30 can be improved. Note that the control unit 40 may control the operation of other devices provided in the toilet room TR based on the detection result of the radio wave sensor 20 . That is, the control unit 40 may operate a lighting device (room light), a sound generating device, a remote controller, and the like provided outside the cabinet body 10 by detecting the toilet lid 230 with the radio wave sensor 20 .

The washbasin 50 is provided, for example, on the top plate (counter) of the cabinet body 10 . The washbasin 50 has a faucet device 51 and a bowl 52 . The bowl 52 is provided below the water discharge portion of the faucet device 51 and receives water discharged from the faucet device 51 . Drainage from the bowl 52 is discharged through a drain pipe (not shown) housed inside the cabinet body 10 to a discharge section (not shown) provided on the wall surface. The wash basin 50 is provided as required and can be omitted.

The paper wrapper 60 holds the toilet paper TP. The paper roll 60 is provided so that the toilet paper TP can be taken out toward the toilet bowl 210 side. The paper winding device 60 is provided as required and can be omitted.

The cabinet 100 and the toilet system 500 according to this embodiment have the configurations as described above. Next, the operation of the lighting section 30 of the cabinet 100 and the toilet system 500 will be described.

FIG. 8 is a flow chart showing control processing when the lighting unit is turned on.
The flow chart shown in FIG. 8 is stored in a storage unit (not shown) of the control unit 40 and repeatedly executed at a predetermined cycle. In addition, each step shown in FIG. 8 shows "step 1" as "S1", for example.

First, in S1, it is determined whether or not there is room entry detection. That is, the control unit 40 determines whether or not the radio wave sensor 20 has detected the user who has entered the toilet room TR. Then, if "YES" in S1, that is, if the radio wave sensor 20 detects that the human body has entered the toilet room TR, the process proceeds to S3, and the illumination unit 30 is turned on. On the other hand, if "NO" in S1, that is, if the radio wave sensor 20 does not detect the entry of the human body into the toilet room TR, the process proceeds to S2.

In S2, it is determined whether or not the toilet lid is detected. That is, the control unit 40 determines whether or not the radio wave sensor 20 has detected the toilet lid 230 . Then, if "YES" in S2, that is, if the radio wave sensor 20 detects the toilet lid 230, the process proceeds to S3, and the lighting section 30 is turned on. On the other hand, if "NO" in S1, that is, if the radio wave sensor 20 does not detect the toilet lid 230, the process ends.

Also, the radio wave sensor 20 detects a human sitting on the toilet seat 220 . As a result, when the user is using the toilet device 200, it is possible to prevent the lighting section 30 from turning off due to a malfunction. Then, when the radio wave sensor 20 detects that the user has left the toilet room TR, the control section 40 turns off the lighting section 30 .

Thus, the cabinet 100 according to this embodiment is placed inside a toilet room TR provided with a toilet bowl 210 having a toilet seat 220 or a toilet lid 230 . A cabinet main body 10 having a storage portion 11 capable of storing articles therein, and a sensor (radio wave sensor 20) provided in the storage portion 11 for detecting a human body in the toilet room TR. is arranged so that the main axis A1 of the sensor passes between the fully closed position and the fully opened position of the toilet seat 220 or the toilet lid 230, and when the sensor detects the toilet seat 220 or the toilet lid 230 , the equipment (lighting unit 30) provided in the toilet room TR operates.

That is, the radio wave sensor 20 detects the toilet lid 230 in addition to detecting the human body. Then, by detecting the toilet lid 230, it is indirectly determined that the human body has entered the toilet room TR, and the illumination unit 30 provided in the toilet room TR operates. Thereby, the interlocking of the entry into the toilet room TR, the operation of opening the toilet lid 230, and the operation of the illumination unit 30 can be improved.

Here, for example, it is conceivable to operate the lighting unit 30 by detection by the human body detection sensor 215 provided in the toilet device 200 . However, in such a case, the automatic lighting system cannot be adopted unless the dedicated toilet device 200 is used, which may limit the options of the toilet device 200 for the consumer. Further, it is conceivable to arrange a human body detection sensor in a cabinet provided on the side of the toilet apparatus, and operate the equipment in the toilet room by detecting the human body by the human body detection sensor. However, depending on the layout of each device in the toilet room and the entrance/exit, it may be difficult to use the entire toilet room as the detection area of the human body detection sensor. As a result, there is a risk that interlocking between the human body's entry into the toilet room, the opening of the toilet lid, and the operation of the toilet room's equipment may be degraded.

Therefore, in the cabinet 100 according to this embodiment, the radio wave sensor 20 detects the turning motion of the toilet lid 230 . Therefore, any toilet apparatus 200 can adopt the automatic lighting system, and the degree of freedom of choice of the toilet apparatus 200 by the consumer can be improved. When the toilet lid 230 is automatically opened by the human body detection sensor 215, the radio wave sensor 20 can indirectly use the detection area of the human body detection sensor 215 in addition to its own detection area. . Therefore, the cabinet 100 according to the present embodiment can improve interlocking between entering the toilet room TR, opening the toilet lid 230, and operating the equipment (lighting unit 30) regardless of the layout of the toilet room TR. can be done.

Further, the sensor is provided in the storage portion 11 located on the rear side of the front end 210 a of the toilet bowl 210 .
