  The toilet seat drive unit 131 is a drive source that rotates the toilet seat 6 based on a toilet seat drive signal from the control device 15, and is, for example, a motor. In the following description, the case where the toilet seat drive unit 131 is a motor will be described, but the present invention is not limited to this and may be a drive source other than the motor.

  The toilet seat drive unit 131 rotates the toilet seat 6 in the forward direction or the reverse direction based on the toilet seat drive signal from the control device 15. Therefore, the toilet seat drive unit 131 positions the toilet seat 6 at a position corresponding to the fully open state of the toilet seat 6 (hereinafter, referred to as “fully open position”) and at a position of the toilet seat 6 corresponding to the fully closed state (hereinafter, “ It is possible to control the toilet seat 6 to be in a fully open state or a fully closed state by rotating the toilet seat 6 from the fully closed position. Here, the position of the toilet seat 6 is, for example, the rotation angle of the toilet seat 6.

  Further, the toilet seat drive unit 131 stops the rotation at an arbitrary position between the fully open position and the fully closed position based on the toilet seat drive signal from the control device 15, and the stopped position, that is, the stopped rotation. The rotation angle of the toilet seat 6 can be locked so as to maintain the angle. That is, the toilet seat drive unit 131 can hold the toilet seat 6 at an arbitrary position between the fully open position and the fully closed position based on the toilet seat drive signal from the control device 15. For example, the toilet seat drive unit 131 can adjust the rotation angle of the toilet seat 6 under the control of the control device 15 to control the rotation angle to an arbitrary rotation angle.

  The output unit 132 has a function of outputting the drive status of the toilet seat drive unit 131. The output unit 132 is, for example, an encoder. The output unit 132 outputs a position pulse corresponding to the rotation of the toilet seat drive unit 131 to the control device 15. For example, the output unit 132 outputs one position pulse to the control device 15 when the toilet seat drive unit 131 makes one rotation. The output unit 132 of the present embodiment is not limited to the encoder, and may be arbitrarily selected as long as the rotation amount of the toilet seat drive unit 131 can be grasped, for example, by measuring the rotation angle of the toilet seat drive unit 131. it can.

  The elevating device 14 elevates and lowers the toilet seat device 4 under the control of the control device 15. For example, the user performs a predetermined operation on the operation unit 2 when cleaning the toilet body 3 (for example, cleaning between the toilet body 3 and the toilet seat device 4), so that the toilet seat device 4 Can be raised. In addition, below, the operation | movement which raises the toilet seat apparatus 4 may be called a lift up operation.

  The control device 15 includes a toilet lid position detection unit 16, a toilet seat position detection unit 17, a setting unit 18, a storage unit 19, and a control unit 20. The control device 15 may be configured by a microprocessor such as a CPU or MPU, a microcontroller such as an MCU, or the like.

  The toilet lid position detection unit 16 detects the current position of the toilet lid 7 (hereinafter referred to as “current position”) based on the position pulse supplied from the output unit 122. For example, the toilet lid position detection unit 16 stores in advance the number of times (hereinafter, referred to as “specified number of times”) of rotating the toilet lid drive unit 121 necessary for the toilet lid 7 to move from the fully closed position to the fully opened position. Remembered in. Therefore, the current position of the toilet lid 7 (for example, the rotation angle) can be specified from the number of position pulses indicating that the toilet lid drive unit 121 has rotated once.

  The toilet seat position detection unit 17 detects the current position of the toilet seat 6 based on the position pulse supplied from the output unit 132. For example, the toilet seat position detection unit 17 stores in advance the prescribed number of times, which is the number of times the toilet seat drive unit 131 is required to rotate the toilet seat 6 from the fully closed position to the fully open position, in the storage unit 19. Therefore, the current position (for example, the rotation angle) of the toilet seat 6 can be specified from the number of position pulses indicating that the toilet seat drive unit 131 has rotated once.

The setting unit 18 sets an arbitrary position between the fully open position and the fully closed position of the toilet seat 6 as the toilet seat setting position. The toilet seat setting position is, for example, the rotation angle of the toilet seat 6 and the rotation angle between the fully open position and the fully closed position of the toilet seat 6.
Further, the setting unit 18 sets an arbitrary position between the fully open position and the fully closed position of the toilet lid 7 as the toilet lid setting position. The toilet lid setting position is, for example, the rotation angle of the toilet lid 7 and the rotation angle between the fully open position and the fully closed position of the toilet lid 7.

For example, when the setting unit 18 acquires a setting signal from the operation unit 2 via the wireless communication unit 9, the setting unit 18 acquires information on the current position of the toilet lid 7 from the toilet lid position detection unit 16 and then acquires the current position. Is set as the toilet lid setting position. Further, the setting unit 18 sets a rotation angle smaller than the set toilet lid setting position by a predetermined rotation angle as the toilet seat setting position.
Then, the setting unit 18 stores the set toilet lid setting position and toilet seat setting position in the storage unit 19.

  The storage unit 19 stores the toilet lid setting position and the toilet seat setting position. Further, the storage unit 19 stores the specified number of times of the toilet lid drive unit 121 and the specified number of times of the toilet seat drive unit 131.

  The control unit 20 controls the rotation of the toilet lid 7 and the toilet seat 6 by controlling the toilet lid opening / closing drive device 12 and the toilet seat opening / closing drive device 13.

Specifically, the control unit 20 rotates the toilet lid 7 to fully open the toilet lid 7 by outputting a toilet lid full open signal to the toilet lid opening / closing drive device 12 to open the toilet lid 7 fully. Control the state.
Further, when the toilet lid setting position is set, the control unit 20 reads the toilet lid setting position from the storage unit 19 and outputs the toilet lid setting position signal including the read information of the toilet lid setting position. Output to the lid opening / closing drive device 12. Accordingly, the control unit 20 can hold the toilet lid 7 at the toilet lid setting position.

The control unit 20 outputs a toilet seat full-open signal for fully opening the toilet seat 6 to the toilet seat opening / closing drive device 13, thereby rotating the toilet seat 6 and controlling the toilet seat 6 in the fully open state.
In addition, when the toilet seat setting position is set, the control unit 20 reads the toilet seat setting position from the storage unit 19 and outputs a toilet seat setting position signal including information on the read toilet seat setting position to the toilet seat opening / closing drive device 13. Output to. Thereby, the control unit 20 can hold the toilet seat 6 at the toilet seat setting position.

Further, when the toilet lid rotation signal for rotating the toilet lid 7 is acquired from the operation unit 2, the control unit 20 outputs the toilet lid drive signal to the toilet lid opening / closing drive device 12. Accordingly, the control unit 20 can rotate the toilet lid 7 by a predetermined amount via the toilet lid opening / closing drive device 12.
Further, when the toilet seat rotation signal for rotating the toilet seat 6 is acquired from the operation unit 2, the control unit 20 outputs the toilet seat drive signal to the toilet seat opening / closing drive device 13. As a result, the control unit 20 can rotate the toilet seat 6 by a predetermined amount via the toilet seat opening / closing drive device 13.

  The control unit 20 outputs a control signal to the lifting device 14 when a lift-up signal instructing a lift-up operation is output from the operation unit 2. Accordingly, the elevating device 14 raises the toilet seat device 4 in the vertical direction when receiving the control signal from the control unit 20.

  Next, a first example of the method of setting the toilet lid setting position according to the present embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating a first example of the method of setting the toilet lid setting position according to the embodiment of the present invention.

For example, as shown in FIG. 3, it is assumed that the toilet device 1 is installed in a toilet room where objects M such as shelves and accessories project from the wall.
In this case, if the toilet lid opening / closing drive device 12 rotates the toilet lid 7 at the fully closed position P ₁ to the fully open position P ₂ , the toilet lid 7 will hit the object M, causing damage to the toilet lid 7. May be Therefore, in this embodiment, when the toilet lid 7 hits the object M, the user sets the toilet lid setting position where the toilet lid 7 does not hit the object M.

  First, when the user sets the toilet lid setting position, the user can sit on the toilet seat 6 and the toilet lid 7 does not contact the object M (hereinafter referred to as “first position”). To move. For example, the user operates the operation unit 2 to rotate the toilet lid 7 to the first position. Specifically, the user can rotate the toilet lid 7 in the opening direction or the closing direction by a predetermined amount by performing the first operation on the operation unit 2. The first operation is not particularly limited as long as it can be uniquely recognized as an operation for instructing to rotate the toilet lid 7 by a predetermined amount, and for example, a simultaneous operation of a plurality of operation switches is possible. Alternatively, it may be operated by operating a dedicated operation switch for moving the toilet lid 7 provided on the operation unit 2.

  When the user performs the first operation on the operation unit 2, the operation unit 2 wirelessly transmits a toilet lid rotation signal to the control device 15. And the control part 20 of the control apparatus 15 will output a toilet lid drive signal to the toilet lid opening / closing drive device 12, if a toilet lid rotation signal is acquired. As a result, the toilet lid opening / closing drive device 12 rotates the toilet lid 7 by a predetermined amount. Therefore, the user can rotate the toilet lid 7 to the first position by performing the first operation on the operation unit 2 until the toilet lid 7 reaches the first position. However, the present invention is not limited to this, and the user may rotate the toilet lid 7 to the first position by directly touching the toilet lid 7 and manually rotating it.

  When the user rotates the toilet lid 7 to the first position, the user performs a second operation on the operation unit 2 to set the current position of the toilet lid 7 to the toilet lid setting position. The second operation is not particularly limited as long as it can be uniquely recognized as an operation for instructing to set the current position of the toilet lid 7 to the toilet lid setting position. For example, a plurality of operation switches May be performed simultaneously, or a dedicated operation switch for setting the toilet lid setting position provided on the operation unit 2 may be operated.

When the second operation is performed, the operation unit 2 wirelessly transmits the setting signal to the control device 15. When the setting signal is acquired, the setting unit 18 of the control device 15 acquires information on the current position of the toilet lid 7 from the toilet lid position detection unit 16 and sets the current position, that is, the first position. Set as the setting position. Then, the setting unit 18 stores the set toilet lid setting position in the storage unit 19. Accordingly, when the toilet lid 7 is rotated, the control unit 20 does not rotate the toilet lid 7 to the fully open position P ₂ but to the toilet lid setting position read from the storage unit 19 to reach the toilet lid setting position. By holding the toilet lid 7, it is possible to prevent the toilet lid 7 from hitting the object M. For example, when the control unit 20 acquires the detection signal from the human body detection unit 10, the control unit 20 reads the toilet lid setting position from the storage unit 19 and outputs the toilet lid setting position signal including the read information of the toilet lid setting position. Output to the toilet lid opening / closing drive device 12. Thereby, the toilet lid opening / closing drive device 12 rotates the toilet lid 7 to the toilet lid setting position, and locks the rotation angle of the toilet lid 7 so that the toilet lid 7 does not move from the toilet lid setting position (for example, , Lock the rotation of the toilet lid drive unit 121). Accordingly, the control unit 20 can hold the toilet lid 7 at the toilet lid setting position.

  Next, a second example of the method of setting the toilet lid setting position according to the present embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a second example of the method of setting the toilet lid setting position according to the embodiment of the present invention.

  For example, as shown in FIG. 4, when the toilet device 1 is installed in a toilet room where objects M such as shelves and accessories project from the wall, the elevating device 14 performs a lift-up operation. Here, from the viewpoint of easy cleaning of the toilet body 3, it is conceivable to control the toilet seat 6 and the toilet lid 7 to be fully open before performing the lift-up operation. However, if the lift-up operation is performed while the toilet seat 6 and the toilet lid 7 are controlled to be fully opened, the toilet lid 7 and the toilet seat 6 may hit the object M, which may cause damage to the toilet lid 7 and the toilet seat 6. Therefore, in the present embodiment, when the toilet lid 7 or the toilet seat 6 hits the object M during the lift-up operation, the user sets the toilet lid 7 or the toilet seat 6 so that the object M does not hit the toilet lid in advance. Set the position and the toilet seat setting position.

  First, when setting the toilet lid setting position, the user can clean between the toilet body 3 and the toilet seat device 4, and the toilet lid 7 does not contact the object M (hereinafter, referred to as " The toilet lid 7 is moved to the "second position". For example, the user operates the operation unit 2 to rotate the toilet lid 7 to the first position. Specifically, the user may rotate the toilet lid 7 to the second position by performing the first operation on the operation unit 2, or by directly touching the toilet lid 7 and manually. The toilet lid 7 may be rotated to the second position by rotating the toilet lid 7.

  When the user rotates the toilet lid 7 to the second position, the user performs the second operation on the operation unit 2 to set the current position of the toilet lid 7 to the toilet lid setting position. When the second operation is performed, the operation unit 2 wirelessly transmits the setting signal to the control device 15. When the setting signal is acquired, the setting unit 18 of the control device 15 acquires information about the current position of the toilet lid 7 from the toilet lid position detection unit 16 and sets the current position, that is, the second position. Set as the setting position. Then, the setting unit 18 stores the set toilet lid setting position in the storage unit 19. Further, the setting unit 18 sets a rotation angle smaller than the toilet lid setting position by a predetermined rotation angle as the toilet seat setting position. For example, this toilet seat setting position is the rotation angle of the toilet seat 6 that allows cleaning between the toilet body 3 and the toilet seat device 4 and does not contact the toilet lid 7. The setting unit 18 stores the set toilet seat setting position in the storage unit 19.

  As a result, the toilet seat device 4 can prevent the toilet lid 7 and the toilet seat 6 from hitting the object M during the lift-up operation. For example, when the user performs a predetermined operation (an operation to instruct a lift-up operation) on the operation unit 2, the operation unit 2 outputs a lift-up instruction signal to instruct the lift-up operation to the control device 15. Upon obtaining the lift-up instruction signal, the control unit 20 reads the toilet lid setting position from the storage unit 19 and outputs the toilet lid setting position signal including the read toilet lid setting position to the toilet lid opening / closing drive device 12. Further, the control unit 20 reads out the toilet seat setting position from the storage unit 19 and outputs a toilet seat setting position signal including the read toilet seat setting position to the toilet seat opening / closing drive device 13. Thereby, the toilet lid opening / closing drive device 12 rotates the toilet lid 7 to the toilet lid setting position, and locks the rotation angle of the toilet lid 7 so that the toilet lid 7 does not move from the toilet lid setting position (for example, , Lock the rotation of the toilet lid drive unit 121). Accordingly, the control unit 20 can hold the toilet lid 7 at the toilet lid setting position. Further, the toilet seat opening / closing drive device 13 rotates the toilet seat 6 to the toilet seat setting position and locks the rotation angle of the toilet seat 6 so that the toilet seat 6 does not move from the toilet seat setting position (for example, rotation of the toilet seat drive unit 131). Lock). Thereby, the control unit 20 can hold the toilet seat 6 at the toilet seat setting position. When the toilet seat 6 is held at the toilet lid setting position and the toilet seat 6 is held at the toilet seat setting position, the control unit 20 outputs a control signal to the lifting device 14. As a result, the lift device 14 lifts up the toilet seat device 4 with the toilet seat 6 held at the toilet lid setting position and the toilet seat 6 held at the toilet seat setting position. Therefore, the lift-up operation can be executed without the toilet lid 7 or the toilet seat 6 hitting the object M.

  Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and includes a design and the like within a range not departing from the gist of the present invention.

(Modification 1) In the above embodiment, the setting unit 18 includes a toilet lid setting position (first toilet lid setting position) for rotating the toilet lid 7 when a detection signal is obtained from the human body detection unit 10, and a lift. The toilet lid setting position (second toilet lid setting position) of the toilet lid 7 that rotates the toilet seat 6 for performing the up operation may be stored in the storage unit 19, respectively. Therefore, when the control unit 20 receives the detection signal from the human body detection unit 10, the control unit 20 reads the first toilet lid setting position from the storage unit 19 and sets the toilet lid setting including the information of the first toilet lid setting position. The position signal may be output to the toilet lid opening / closing drive device 12. When the lift-up instruction signal is acquired from the operation unit 2, the control unit 20 reads the second toilet lid setting position from the storage unit 19 and includes the read information of the second toilet lid setting position. The toilet lid setting position signal may be output to the toilet lid opening / closing drive device 12.
However, the setting unit 18 does not necessarily have to set the first toilet lid setting position and the second toilet lid setting position, and may set at least one of them. Therefore, when the first toilet lid setting position is not set, when the control unit 20 obtains the detection signal from the human body detection unit 10, the control unit 20 outputs the toilet lid fully open signal to the toilet lid opening / closing drive device 12. As a result, the toilet lid 7 is rotated to the fully open position.

(Modification 2) In the above embodiment, the case where the toilet seat device 4 has the toilet seat 6 and the toilet lid 7 as the rotating members has been described, but the present invention is not limited to this, and the toilet seat device 4 serves as the rotating member. You may have only the toilet seat 6. In this case, the method of setting the toilet seat setting position of the toilet seat 6 may be the same as the method of setting the toilet lid 7 (for example, the setting method described in the first example or the second example). ..

(Modification 3) In the above embodiment, an example in which the set position stored in the storage unit 19 is used when performing the lift-up operation or when the detection signal is acquired from the human body detection unit 10 has been described. The present invention is not limited to this, and the use of the set position stored in the storage unit 19 is not particularly limited. That is, according to the present invention, at least one of the rotating members of the toilet lid 7 and the toilet seat 6 is set as an arbitrary position between the fully open position and the fully closed position, and the rotating member is held at the setting position. It suffices to have a configuration to do so.

(Modification 4) In the above embodiment, the toilet lid setting position or the toilet seat setting position may be automatically set. For example, the control device 15 may include a learning mode for learning the toilet lid setting position and the toilet seat setting position. Then, when the learning mode is executed, the control unit 20 may rotate the rotating member of at least one of the toilet lid 7 and the toilet seat 6 between the fully open position and the fully closed position. Then, the setting unit 18 detects the load applied to the rotating member during the learning mode, and when the load increases compared to the normal open / closed state (for example, when the load exceeds the threshold value). Alternatively, a turning angle smaller than the turning angle of the turning member when the load increases by a predetermined angle may be set as the set position of the turning member. The case where the load exceeds the threshold means that the rotation speed of the drive source (the toilet lid drive unit 121 or the toilet seat drive unit 131) of the rotating member is below the threshold value, or the current flowing through the drive source exceeds the threshold value. There are cases. The normal open / closed state means that, for example, when the rotating member is rotated between the fully open position and the fully closed position, an object M such as a shelf or an accessory is in contact with the rotating member. There is no state.
Therefore, the threshold value distinguishes the load in the normal open / closed state from the load in the state in which the rotating member is overloaded by the contact of the object M such as a shelf or an accessory with the rotating member. It may be set to a possible value. Here, the load applied to the rotating member may be a load applied to a motor driven by the rotating member (hereinafter referred to as “motor load”). For example, an encoder that outputs a pulse signal according to the rotation of the motor is provided in the motor. Then, the control unit 20 may measure the motor load based on the pulse signal acquired from the encoder. For example, the motor load is the pulse width of the pulse signal, the rotation speed of the motor, or the rotation speed.

  As described above, in the toilet seat device 4 of the present embodiment, at least one of the toilet seat 6 and the toilet lid 7, which is pivotally supported between the fully open position and the fully closed position, and its rotating member. A setting unit 18 that sets an arbitrary position between the fully open position and the front fully closed position of the rotating member as a setting position, and a control unit 20 that controls the rotation of the rotating member are provided. Then, for example, when a condition (for example) such as a case where a detection signal is acquired from the human body detection unit 10 or a case where a lift-up instruction signal is acquired is satisfied, the control unit 20 sets the rotating member to the set position. Hold.

  According to such a configuration, it is possible to prevent the toilet seat 6 and the toilet lid 7 from coming into contact with the shelves and accessories protruding from the wall.

  Further, the toilet seat device 4 of the above-described embodiment may include an elevating device 14 that elevates and lowers the toilet seat device 4. When the lifting device 14 raises the toilet seat device 4, the control unit 20 may rotate the rotating member and hold the rotating member at the set position.

  According to such a configuration, when the user cleans the toilet body 3, even when the toilet seat device 4 is lifted up, the toilet seat 6 and the toilet lid 7 are attached to the shelves and accessories protruding from the wall. The contact can be suppressed.

  Further, the toilet seat device 4 of the above embodiment may include the human body detection unit 10 that detects a user. Then, when the human body detection unit 10 detects the user, the control unit 20 may rotate the rotating member from the fully closed position and hold the rotating member at the set position.

  According to such a configuration, when the user uses the toilet device 1, the control unit 20 controls the shelves and the accessories protruding from the wall even when the toilet lid 7 is rotated to be in the open state. It is possible to prevent the toilet lid 7 from coming into contact with.

  Further, the toilet seat device 4 of the above-described embodiment rotates the rotating member in the opening direction during execution of the learning mode, and when the load applied to the rotating member is increased as compared with the normal open / closed state. The set position may be a turning angle that is smaller than the turning angle of the turning member when the load increases by a predetermined angle.

  According to such a configuration, the user does not need to set the setting position of the rotating member, which is convenient.
