[First Embodiment]
FIG. 1 shows an example of a heated toilet seat device S according to the present invention. However, in the drawing, only a portion related to the present invention is schematically shown in the internal structure of the heating toilet seat device S. The heating toilet seat device S includes a toilet seat 1 in which heating means H such as a heater is incorporated, and a toilet seat support 10 that is installed on the upper surface of a toilet bowl (not shown) and supports the toilet seat 1 in a swingable manner. . In this example, mounting arm portions 2 and 2 are provided on the left and right sides of the rear end portion of the toilet seat 1 so as to protrude rearward at a predetermined interval, and the front surface of the toilet seat support 10 is provided between the mounting arm portions 2 and 2. It is comprised so that the bulging part 11 provided in the part may be pinched | interposed. The shaft mounting portions 3 and 4 provided on the left and right mounting arm portions 2 and 2 of the toilet seat 1 are detachable from the support shafts 20 and 21 protruding from the left and right side surfaces of the bulging portion 11 of the toilet seat support 10. It was configured to be installed. Further, at least one shaft mounting portion 4 in the toilet seat 1 is provided with a lock mechanism 5 for preventing separation from the support shaft 20.

  The toilet seat support 10 has, for example, a box shape, and a support-side control unit C1 that is connected to a power source W and receives power supply is provided therein. First support means X for detecting whether the toilet seat 1 is attached to the toilet seat support 10 is connected to the support-side control unit C1. In this example, the first detection means X is arranged on both the left and right sides, but only one may be provided. Based on the presence or absence of a detection signal output from the first detection means X, the support-side control unit C1 executes or stops power transmission to the toilet seat. Although illustration is omitted, the amount of energization to the toilet seat 1 is controlled based on information input from the operation panel or the like, and the toilet seat temperature is adjusted.

  Inside the toilet seat 1 is a heating means H, a temperature sensor T composed of a combination of a planar heater or induction coil and metal foil, and power distribution from the power supply device 30 to be described later to the heating means H or the temperature sensor T. A toilet seat side control unit C2 is provided. One shaft mounting portion 4 is provided with second detection means Y that detects whether or not the lock mechanism 5 is in a locked state that prevents the shaft mounting portion 4 and the support shaft 20 from being separated. The toilet seat side control unit C2 is set to execute or stop power distribution from the power supply device 30 to the heating unit H based on the presence or absence of a detection signal output from the second detection unit Y. Further, the toilet seat side control unit C2 has a function of adjusting the energization state to the heating means H based on the detected temperature signal of the temperature sensor T or stopping power transmission when an abnormal temperature rise is detected.

  As shown in FIG. 1, the power feeding device 30 of the present example is disposed at the bulging portion 11 of the toilet seat support 10 and has a primary core K1 wound around the outer periphery of the primary coil L1 and a rear end portion of the toilet seat 1. The secondary core K2 is wound around the secondary coil L2. The primary coil L1 is connected to the support body side control part C1, and the secondary coil L2 is connected to the toilet seat side control part C2. The cores K1 and K2 are U-shaped, and the configuration in which the coils L1 and L2 are wound around the intermediate portion is illustrated, but the present invention is not limited to this. When the toilet seat 1 is in the prone position (position where the user can sit), the end surface of the primary core K1 and the end surface of the secondary core K2 are close to each other and face each other. Then, when AC power having an appropriate frequency is applied from the support-side controller C1 to the primary coil L1, an electromotive force is generated in the secondary coil L2 due to the mutual induction action. Further, this electric power is adjusted by the toilet seat side control unit C2 and supplied to the heating means H to raise the temperature of the toilet seat 1 surface to a desired temperature.

  The first detection means X for detecting whether or not the shaft mounting portions 3 and 4 of the toilet seat 1 are mounted on the support shafts 20 and 21 of the toilet seat support 10 may be configured as illustrated in FIG. 2 shows the first detection means X provided in one shaft mounting portion 3, the other shaft mounting portion 4 may have the same configuration as the detection means X in FIG. It can be omitted.

  The first detection means X shown in FIG. 2A embeds a magnet Mx in a portion close to the toilet seat support 10 in the shaft mounting portion 3 of the toilet seat 1, and the magnet in the toilet seat support 10 (bulging portion 11). A sensor Sx serving as a signal output unit is disposed at a portion facing Mx. The sensor Sx is composed of a magnetic sensor using a Hall element or a magnetoresistive element. The first detection means X shown in FIGS. (B) and (C) is a sensor in which a sensor Sx is disposed in a support shaft 21 and a magnet Mx is embedded in a portion close to the support shaft 21 in the shaft mounting portion 3. FIG. 4B shows an example in which the magnet Mx is arranged on the side of the support shaft 21, and FIG. 4C shows an example in which the magnet Mx is arranged on the axial extension line of the support shaft 21. In any of these exemplified first detection means X, when the shaft mounting portion 3 of the toilet seat 1 is mounted on the support shaft 21 of the toilet seat support 10, the magnet Mx approaches the detection area of the sensor Sx, thereby causing the sensor Sx. Detects a change in magnetic force and outputs a detection signal to the support side control unit C1. The support body side control unit C1 enables power transmission to the power feeding device 30 based on the detection signal. In the state where the toilet seat 1 is detached from the support shaft 21, the first detection means X does not output a detection signal, so the support-side control unit C <b> 1 disables power transmission to the power supply device 30. That is, since the support body side control unit C1 does not energize the primary coil L1, no mutual induction action occurs between the primary coil and the secondary coil, and therefore no power is supplied to the toilet seat side control unit C2. .

  A lock mechanism 5 that prevents the shaft mounting portion 4 of the toilet seat 1 from being separated from the support shaft 20 of the toilet seat support 10, and a lock state in which the lock mechanism 5 prevents the shaft mounting portion 4 and the support shaft 20 from being separated. For example, the second detection means Y for detecting whether or not there is the following is configured as follows. As shown in FIG. 3, the shaft mounting portion 4 is formed with a storage space 4a for storing the support shaft 21 and an opening 4b for guiding the support shaft 21 into the storage space 4a. The lock mechanism 5 is composed of a movable member that rotates along the side peripheral surface of the shaft mounting portion 4. The movable member has a C shape having a notch 5a, and a knob 5b for rotating operation is provided at an appropriate position. The second detection means Y includes a magnetic sensor S1 as a signal output unit composed of a Hall element or a magnetoresistive element disposed in the shaft mounting portion 4, a magnet M1 disposed at an appropriate position of the lock mechanism 5, and a support shaft. 20 and a magnet M2 disposed in the inside. When the lock mechanism 5 is in the locked state (see FIG. 3B), the two magnets M1 and M2 are disposed so as to face each other with the front and back surfaces of the magnetic sensor S1 interposed therebetween.

  The second detection means Y operates as follows. As shown in FIG. 4A, when the shaft mounting portion 4 is in a state before being mounted on the support shaft 20, the lock mechanism 5 has the opening 4b of the shaft mounting portion 4 positioned in the notch 5a. It is set as follows. At this time, since neither of the magnets M1 and M2 is close to the magnetic sensor S1, the magnetic sensor S1 does not detect a magnetic field change and does not output a signal. As shown in FIG. 5B, when the support shaft 20 is mounted in the opening 4a of the shaft mounting portion 4, the magnet M2 in the support shaft 20 approaches the magnetic sensor S1, so that magnetism acts on the magnetic sensor S1. Thus, the magnetic sensor S1 can detect a change in the magnetic field and output a detection signal for detecting that the support shaft 20 is mounted. However, the support shaft detection signal output at this stage is not necessarily adopted.

  Next, as shown in FIG. 4C, the lock mechanism 5 is rotated to close the opening 4 b of the shaft mounting portion 4. As a result, separation between the shaft mounting portion 4 and the support shaft 20 is prevented. At this time, the magnetic sensor S1 detects a magnetic change larger than that in the case of FIG. This is because the magnets M1 and M2 are positioned so as to face each other in a straight line across the front and back surfaces of the magnetic sensor S1, and as a result, the magnetic fields of the magnets M1 and M2 are aligned, so that a strong magnetic field acts on the magnetic sensor S1. It is. The magnetic sensor S1 detects this magnetic change and outputs a detection signal to the toilet seat side control unit C2. The toilet seat side control unit C2 operates to enable power supply to the heating means H based on this detection signal. When the lock mechanism 5 is not in the locked state, the magnetic sensor S1 of the second detection means Y does not output the detection signal, so power supply to the heating means H is disabled.

  With the mechanism as described above, the heating toilet seat device S according to the present invention has the shaft mounting portions 3, 4 of the toilet seat 1 mounted on the support shafts 20, 21 of the toilet seat support 10, and the lock mechanism 5 rotates the shaft. When the mounting portion 4 and the support shaft 20 are in a locked state in which separation is prevented, power can be supplied from the power supply device 30 to the heating means H in the toilet seat 1, and in other states, power can be supplied to the heating means H. Since it is impossible, it is excellent in safety.

  If the sensors Sx and S1 in the first detection means X and the second detection means Y are common sensor elements, the number of parts can be reduced, resulting in cost reduction and management labor reduction. It is.

[Second Embodiment]
The second detection means Y that detects whether or not the lock mechanism 5 is in a locked state that prevents the shaft mounting portion 4 and the support shaft 20 from being separated may be configured as shown in FIG. In this example, a magnetic sensor S1 using a Hall element or a magnetoresistive element is disposed inside the support shaft 20, and the magnets M1, M1 are disposed at positions close to the support shaft 20 in the lock mechanism 5 and the shaft mounting portion 4, respectively. M2 was disposed. With this configuration, when the lock mechanism 5 is rotated from the unlocked state shown in FIG. 5A to the locked state shown in FIG. 5B, the magnets M1 and M2 sandwich the front and back surfaces of the magnetic sensor S1. As a result, the magnetic field acting on the magnetic sensor S1 becomes stronger. The magnetic sensor S1 detects this large magnetic change and outputs a detection signal.

  In this example, since the magnetic sensor S1 of the second detection means is disposed in the support shaft 20, when the lock mechanism 5 is in the locked state, a detection signal is output to the support side control unit C1. Composed. Therefore, when the lock mechanism 5 is not in the locked state and no detection signal is output from the second detection unit, the support-side control unit C1 stops power transmission. That is, since the support side control unit C1 does not energize the primary coil L1, the primary coil L1 does not generate a magnetic field. Therefore, since the magnetic flux does not leak from the coil, there is no adverse effect when the magnetic card or IC card is brought near by mistake, and there is no risk of generating heat even when a metal object such as a coil is brought close. Can demonstrate safety.

  Even in the present embodiment, if the sensors Sx and S1 in the first detection means X and the second detection means Y are common sensor elements, the number of parts can be reduced, and the cost can be reduced and management labor can be reduced. Will be reduced.

[Third Embodiment]
In FIG. 6, the sensor of the second detection means Y is constituted by a reed switch S2. In this example, a sensor (reed switch) S <b> 2 is disposed in the shaft mounting portion 4 of the toilet seat 1, and a magnet M <b> 1 is disposed at an appropriate position of the lock mechanism 5. When the lock mechanism 5 is in the locked position (see FIG. 6A), the reed switch S2 and the magnet M1 are close to each other and the shaft mounting portion 4 can be detached from the support shaft 20 (FIG. 6 ( B)), and the magnet M1 was set to be separated from the reed switch S2. Even in this example, since the second detection means Y outputs a detection signal only when the lock mechanism 5 is in the locked state, power is not supplied to the heating means H in the toilet seat 1 in the unlocked state. , Can ensure safety.

[Fourth Embodiment]
In FIG. 7, the second detection means Y is constituted by a limit switch S3. In this example, the limit switch S3 is disposed so that the actuator portion d protrudes from the outer peripheral surface of the shaft mounting portion 4 of the toilet seat 1. When the lock mechanism 5 is in the locked position (see FIG. 7A), the actuator portion d of the limit switch S3 is located in the notch 5a of the lock mechanism 5, and the shaft mounting portion extends from the support shaft 20. 4 was set so that the actuator portion d of the limit switch S3 was in contact with the inner peripheral surface of the lock mechanism 5 when it was in a non-locking state in which 4 was removable (see FIG. 7B). In this example, when the limit switch S3 as the second detection means Y is in the unlocked state, the actuator portion d is pressed by the lock mechanism 5 and is in the ON state. When the lock mechanism 5 is in the locked state, the actuator portion d is released and the limit switch S3 is shifted to the OFF state. Therefore, the second detection means Y in the present embodiment is such that the switching of the OFF / ON state of the limit switch S3 is output as a detection signal.

[Fifth Embodiment]
8 to 11 show different structural examples of the lock mechanism 30. FIG. The lock mechanism 30 is configured by an elastically swinging lever 33 and is provided in the attachment arm portion 2 of the toilet seat 1. A button portion 31 that is urged outward by a spring 35 is provided at one end of a lever 33 that is swingably supported by a pin 32, and a hook portion 34 is formed at the other end. And the magnetic sensor Sx which comprises the 1st detection means X is arrange | positioned in the vicinity of the support shaft 20 in the toilet seat support body 10, and the magnet Mx corresponding to this is accommodated in the storage space 40a in the shaft mounting part 40 of the toilet seat 1. Provided at a position close to On the other hand, the magnetic sensor S4 constituting the second detection means Y is disposed near the button part 31 in the initial position, and the magnet M4 corresponding thereto is disposed on the button part 31. In addition, the leaf | plate spring 50 is arrange | positioned at the terminal part of the storage space 40a.

  As shown in FIG. 8, the lock mechanism 30 having such a configuration has the sensor Sx and the magnet Mx constituting the first detection means X separated when the toilet seat is detached from the toilet seat support 10. The first detection means does not output a detection signal, and therefore the primary coil L1 is not excited. Subsequently, as shown in FIG. 9, the support shaft 2 is inserted into the storage space 40 a of the shaft mounting portion 40. As a result, the tip of the hook portion 34 in the lock mechanism 30 is pushed to the left and right by the support shaft 20. In the intermediate state shown in the figure, as a result of the lever 33 swinging, the button portion 31 moves inward against the spring 35, so that the sensor S4 and the magnet M4 constituting the second detection means Y are separated. Therefore, no detection signal is output from the second detection means Y.

  As shown in FIG. 10, when the support shaft 20 is pushed to the end of the storage space 40 a, the hook portion 34 of the lock mechanism 30 abuts and supports the bottom surface of the support shaft 20 without sandwiching the side surface of the support shaft 20. It becomes. This state is a locked state in which the hook portion 34 of the lock mechanism 30 prevents the dropping from the support shaft 20. At this time, as shown in FIG. 11, since the toilet seat side magnet Mx comes close to the toilet seat support 10 side sensor Sx, the sensor Sx detects a magnetic field change (increase in magnetic force), and the first detection means. X outputs a detection signal. In addition, the lever 33 of the lock mechanism 30 is returned and swung by the urging force of the spring 35 to return the button unit 31 to the initial position. As a result, the magnet M4 of the button part 31 is positioned close to and opposed to the sensor S4, so that the sensor S4 detects a change in the magnetic field and outputs a detection signal from the second detection means Y. When the lock mechanism 30 is in the locked state as described above, the first and second detection means X and Y both output detection signals, so that power is supplied from the toilet seat support 10 to the heater in the toilet seat 1. It becomes possible.

  When removing the toilet seat 1 from the toilet seat support 10, in the state shown in FIG. 10, the lever 33 is swung by pushing the button portion 31, and the hooks 34, 34 at the distal end portion are opened. As a result, the support shaft 20 can be extracted from the storage space 40a.
