  Hereinafter, a toilet apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a toilet apparatus 1 according to the present embodiment. As shown in FIG. 1, a toilet device 1 includes a main body portion 11 having a film seal device therein, a toilet seat portion 12 installed on the upper surface of the main body portion 11, and an opening portion 13 provided directly below the toilet seat portion 12. And an instruction controller 14 for giving an instruction to the film sealing device of the main body 11.

  FIG. 2 is a block diagram illustrating a configuration of the toilet apparatus 1. FIG. 3 is a view showing a main part of the toilet apparatus 1. As shown in FIGS. 2 and 3, the main body 11 includes a control unit 111, a film feeder 112, a drive unit 113, a heater 114, a light sensor 115 as a sensor, a speaker 116, as a film sealing device, Is provided.

  The control unit 111 includes an arithmetic device such as a CPU (central processing unit).

  The film feeder 112 includes a diaphragm unit that narrows the film F, and a feed roller that draws the film F downward from the film cassette 31.

  The drive unit 113 includes a stepping motor, and drives the aperture unit and the feed roller based on a control signal from the control unit 111.

  The heater 114 is displaced in conjunction with the throttle portion. The heater 114 abuts on the pressure-bonding portion 32 formed of rubber or the like, heats the film F, and cuts the film 33 containing the contents.

  The optical sensor 115 detects an end mark installed at the end portion of the film F. The optical sensor 115 is disposed at a position where the end mark can be detected. The optical sensor 115 is provided at the bottom of the film cassette 31 formed of a material that transmits light, such as polypropylene. When the film cassette 31 is formed of a material that does not transmit light, the optical sensor 115 is disposed at a position corresponding to, for example, a through hole provided at the bottom of the film cassette 31. The through hole is provided at a position where the reflection portion R, which is an end mark installed near the end portion of the film F, can be detected when the film is almost gone.

  The optical sensor 115 includes, for example, a light emitting unit that emits light and a light receiving unit that generates an ON signal when light is detected. When the reflection unit R comes to a position corresponding to the optical sensor 115, the light emitted from the issuing unit is reflected by the reflection unit R and reaches the light receiving unit, and the light receiving unit outputs an ON signal to the control unit 111.

  The instruction controller 14 includes a film feed switch 141 that instructs the control unit 111 to feed the film F, and a cut switch 142 that is an operation switch that instructs the control unit 111 to cut the film F.

  The film feed switch 141 is turned on when the user needs to send the film F. In addition, the cut switch 142 is turned on after the user adds a function. When the cut switch 142 is turned on, the toilet apparatus 1 squeezes the film F by the squeezing unit, cuts the film F by the heater 114 by heat, and further feeds the film F back to the use position by the feed roller. Run the sequence.

  The speaker 116 generates sound according to instructions from the control unit 111.

  As shown in FIG. 3, when the film F is sufficiently filled in the film cassette 31, the reflection portion R installed in the vicinity of the end portion of the film F is detected.

  FIG. 4 is an enlarged view of a portion A in FIG. 3 when the film F is reduced. As shown in FIG. 4, even if the film F is slightly reduced, the reflection portion R installed in the vicinity of the end portion of the film F is in a range corresponding to the optical sensor 115. Accordingly, also in this case, the optical sensor 115 outputs an ON signal to the control unit 111.

  Here, the vicinity of the end portion of the film F means a position where a length sufficient to use the toilet device 1 is left several times from the end portion of the film F.

  While the reflection part R is at a position corresponding to the optical sensor 115, the reflection part R reflects the light emitted from the optical sensor 115 toward the light receiving part. The light receiving unit outputs an ON signal to the control unit 111 when detecting the reflected light. The control unit 111 can determine that the film F still remains based on the ON signal.

  FIG. 5 is a diagram illustrating a state where the film F is exhausted. As shown in FIG. 5, when the film F runs out, the reflection portion R moves away from the optical sensor 115. In this case, since the light receiving unit of the optical sensor 115 does not detect the reflected light, the output signal changes from ON to OFF. That is, the control unit 111 detects that the output signal from the optical sensor 115 has changed from ON to OFF when the reflecting unit R installed near the terminal end of the film F moves away from the optical sensor 115, and Detects near the end.

  FIG. 6 is a diagram showing the reflection portion R installed on the film F. As shown in FIG. As shown in FIG. 6, the reflecting portion R is installed at a lower folded portion near the end portion of the film F.

  A plurality of films F are folded back and stored in the film cassette 31 in the vertical direction. That is, the film F extends from the upper side to the lower side, is folded at the lower end portion and extends upward, and is folded at the upper end portion and extends downward. Thereafter, this folding is repeated and the film F is accommodated in the film cassette 31.

  FIG. 7 is a diagram showing an end mark according to an application example. As shown in FIG. 7, the end mark may be a black mark B which is a black streak provided along the longitudinal direction of the film F.

  In this case, the optical sensor 115 is arranged in the side surface direction of the film cassette, and the film cassette 31 is provided with a through hole at a position corresponding to the optical sensor 115 and the black mark B.

  As long as the film F is sufficient, light emitted from the issuing unit of the optical sensor 115 is reflected by the film F and reaches the light receiving unit, and the optical sensor 115 outputs an ON signal to the control unit 111.

  When the film F disappears and the black mark B appears, the light of the optical sensor 115 is absorbed by the black mark B, so that the reflected light is not detected and the optical sensor 115 outputs an OFF signal to the control unit 111.

  Therefore, the control unit 111 can detect the film end by detecting the black mark B by the optical sensor 115.

  FIG. 8 is a flowchart showing the film end detection operation by the control unit 111 of the toilet apparatus 1.

  As shown in FIG. 8, in step 801, the control unit 111 detects whether the operation switch is turned on.

  In step 802, if the control unit 111 determines that the operation switch is turned on (Y in step 802), the control unit 111 proceeds to step 803. If it is determined that the operation switch is not turned on (N in step 802), the control unit 111 returns to step 801.

  In step 803, the control unit 111 performs a film end detection operation. That is, the control unit 111 detects a film end near the end of the film F by determining whether an end mark is detected based on the output of the optical sensor 115.

  In step 804, the control unit 111 determines whether a film end has been detected. When it is determined that the film end has been detected (Y in Step 804), the control unit 111 proceeds to Step 805, and when it is not determined that it has been detected (N in Step 804), the control unit 111 proceeds to Step 806.

  In step 805, the control unit 111 outputs a sound prompting the replacement of the film F from the speaker 116, and the process returns to step 801. That is, if detected, the control unit 111 stops the cut sequence and notifies the user of the film end.

  In step 806, the control unit 111 performs a film F feeding process.

  In step 807, the control unit 111 performs a film end detection operation.

  In step 808, the control unit 111 determines whether a film end has been detected. When it is determined that the film end has been detected (Y in Step 808), the control unit 111 proceeds to Step 809, and when it is not determined that it has been detected (N in Step 808), the control unit 111 proceeds to Step 810.

  In step 809, the control unit 111 outputs a sound indicating that the film F has run out from the speaker 116, and returns to step 801. That is, if detected, the control unit 111 stops the cut sequence and notifies the user of the film end.

  In step 810, the control unit 111 performs a film F welding process. That is, the control unit 111 welds the film F with the heater 114 and then cuts the film F with heat.

  In step 811, a film end detection operation is performed.

  In step 812, the control unit 111 determines whether a film end has been detected. When it is determined that the film end has been detected (Y in Step 812), the control unit 111 proceeds to Step 813. When it is not determined that the film end has been detected (N in Step 812), the control unit 111 returns to Step 801.

  In step 813, the control unit 111 outputs a sound prompting replacement of the film F from the speaker 116, and the process returns to step 801. That is, if detected, the control unit 111 stops the cut sequence and notifies the user of the film end.

  As described above, the toilet apparatus 1 includes the toilet seat portion 12, the film accommodating portion (film cassette 31) that is disposed below the toilet seat portion 12 and accommodates the film F formed in a cylindrical shape, and the film accommodating portion. When the film feeder that feeds the film F from the part, the heater 114 that welds and cuts the fed film, and the terminal part of the film F approach, the terminal part of the film F approaches A sensor (optical sensor 115) that outputs a signal indicating that the film has been detected, and the film feeder so that the film F is not fed when it is detected that the end of the film is approaching based on the output of the sensor. And a control unit 111 for controlling.

  Further, the toilet apparatus 1 of the present embodiment includes a toilet seat portion 12 and a film accommodating portion (film cassette) that accommodates a film F that is disposed below the toilet seat portion 12 and is formed in a cylindrical shape and provided with an end mark near the end portion. 31), a film feeder that feeds the film F from the film container, a heater 114 that welds and cuts the fed film F, and the end mark is not detected when the film F is sufficiently filled, When the film F is detected based on the output of the optical sensor 115 and the output of the optical sensor 115, the control is performed so that the film F is not fed. And a control unit 111.

  Therefore, there is an effect that it is possible to provide a toilet device that can surely notify the user when the film is about to run out and can prevent misuse.

  Any sensor can be used as long as it can detect that the film F is remaining.

  FIG. 9 is a diagram illustrating an example in which a contact sensor 115A is used as a sensor. As shown in FIG. 9, the contact sensor 115A is installed on the inner wall of the film cassette 31, for example. In this case, the contact sensor 115A outputs an ON signal when the film F is sufficient, and outputs an OFF signal when the film F decreases.

  FIG. 10 is a diagram illustrating an example in which a transmissive optical sensor is used as a sensor. As shown in FIG. 10, the transmissive optical sensor includes a light emitting unit 115B and a light receiving unit 115C. The film F is disposed between the light emitting unit 115B and the light receiving unit 115C. In this case, the light-receiving unit 115C outputs an OFF signal when the film F is sufficient, and an ON signal when the film F runs out.

  FIG. 11 is a diagram illustrating an example in which a magnetic sensor 115D is used as a sensor. As shown in FIG. 11, the magnetic body M is installed as an end mark in a lower folded portion near the end portion of the film F. The magnetic sensor 115D is arranged at the bottom of the ring-shaped film cassette 31 so as to be shifted from the radial center of the bottom toward the end of the film F. In this case, the contact sensor 115A outputs an ON signal when the film F is sufficient, and outputs an OFF signal when the film F decreases.

  In any of the above cases, the operation described with reference to FIG. 8 is the same.
