(Embodiment 1)
1 is a perspective view showing a state in which the heated toilet seat according to Embodiment 1 of the present invention is attached to a toilet bowl, FIG. 2 is a perspective view showing a state in which the toilet seat is detached from the toilet bowl, and FIGS. FIG.

  In FIG. 1, the heating toilet seat 10 is attached to be fixed to the toilet 12, supports the rotation of the toilet seat 13 and receives power from the power supply 14 through the power cord 17, and the toilet seat 13 including the heating means 15. , A connector 16 (support means side connector and toilet seat side connector) for transmitting electric energy supplied from the power source to the heating means 15 of the toilet seat 13 is provided. The toilet bowl 12 includes a toilet seat cover that covers the entire surface of the toilet bowl 12 and the toilet seat 13 by moving up and down like the toilet seat 13, but the illustration thereof is omitted.

  In FIG. 2, the support means 11 includes a support means side connector 18 having an electrical contact portion 19 for supplying electricity to the heating means 15 of the toilet seat 13, and a rotation bearing for supporting the rotation of the toilet seat 13 and the toilet seat lid. 20 is provided. 2 shows a state in which the toilet seat 13 is removed from the toilet bowl 12 and the support means side connector 18 can be seen in the table, but the support means side connector can be used even when the toilet seat 13 is attached to the toilet bowl 12 and the toilet seat 13 is raised. 18 becomes the state which looks like a table similarly.

  In FIG. 3, the toilet seat 13 is for attaching to the toilet seat side connector 21 having the electrical contact portion 19 for receiving the supply of electricity from the support means 11 to the heating means 15, and for attaching to the support means 11, and the toilet seat 13 itself rotates. And a detaching means 23 for detaching the toilet seat 13 from the support means 11.

  In FIG. 4, the toilet seat 13 includes a radiant heating element 24 as heating means. FIG. 5 is a main cross-sectional view of the toilet seat 13. Inside the cavity portion 27 is a radiation reflecting plate 28 having a mirror-finished aluminum plate facing the seating portion 25 of the toilet seat 13, and a lamp heater as a radiation-type heating element. 29.

  In the vicinity of the lamp heater 29, a thermostat 30 and a cord-shaped thermal fuse 31 connected in series with the lamp heater 29 are provided to prevent an excessive temperature rise in the event of an unsafe situation. The thermal fuse 31 is provided along the lamp heater 29 so as to keep the distance from the plurality of lamp heaters 29 constant.

  The lamp heater 29 is configured by penetrating a filament 33 made of tungsten and enclosing a halogen gas 34 inside a glass tube 32, and repeats a halogen cycle reaction for forming tungsten halide as the filament 33 generates heat. This prevents the filament 33 from being consumed. As a result, the filament 33 having a very small heat capacity can be used as the heat source, and the radiation energy can be caused to rise very steeply.

  The lamp heater 29 is fixed to the radiation reflecting plate 28 by a lamp heater fixture 36 having a rubber bush 35 which is an elastic material, and the radiation reflecting plate 28 is fixed to the case 26 by rubber feet 37. Reference numeral 38 denotes a seating detection means composed of a micro switch 40 provided in the leg rubber 39 of the toilet seat 13, and detects the seating of the user when the switch is turned on by applying a load to the toilet seat 13. . The temperature during heating is controlled by the thermistor 41. Reference numerals 42 and 43 denote a human body detection sensor for detecting that the user has entered the toilet and a control means.

  FIG. 6 shows a connector. Here, the electrical contact portion 19 of the support means side connector 18 has a partially concave shape, and the electrical contact portion 19 of the heating means side connector 21 has a convex shape, and these contact each other.

  About the heating toilet seat comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The support means 11 is attached so as to be fixed to the toilet bowl, and is supplied with electricity from the power source 14. The toilet seat 13 is pivotable and attached to the support means 11 so as to be removable, and freely pivots up and down. Here, when the toilet seat 13 is lowered, the toilet seat side connector 21 provided on the toilet seat 13 for supplying power to the heating means 15 and the support means side connector 18 provided on the support means are engaged with each other. The electric contacts are brought into contact with each other, whereby the electric power supplied to the support means is supplied to the heating means 15 provided in the toilet seat 13, and the heating means 15 functions.

  On the other hand, when the toilet seat 13 is in the raised state, or when the male user raises the toilet seat 13 for urination after entering the room, the toilet seat side connector 21 and the support means side connector 18 are separated from each other, so that no power is supplied. Electric power is not supplied to the heating means 15. Thereby, it is economical because the toilet seat 13 is not heated more than necessary, energy is saved, and the electricity bill is inexpensive.

  Next, a mechanism for raising the temperature of the toilet seat by the radiation type heating element 24 will be described. When the user enters the toilet with the toilet seat 13 lowered, the human body detection sensor 42 detects this and a signal is sent to the control means 43, and the control means 43 starts energizing the lamp heater 29. The input energy is instantaneously converted into radiant energy, radiated upward from the filament 33 through the glass tube 32 and the radiation reflector 28, and contributes to the temperature increase of the toilet seat 13. Here, the end portion of the radiation reflecting plate 28 has an upward bent portion over the entire circumference, and the heat radiation from the lamp heater 29 is deflected by the bent portion. It acts to increase the radiation density at the peripheral edge and the inner peripheral edge, thereby achieving a uniform radiation distribution to the upper part of the toilet seat 13. Normally, since it takes 6 to 8 seconds on average from detecting a person by the human body detection sensor 42 to sitting on the toilet seat 13, the temperature can be sufficiently increased in this system. If the radiant heating element 24 is used as described above, the warming surface of the seating portion 25 of the toilet seat 13 can be heated almost instantaneously, so there is no need to keep the heater energized, that is, the toilet seat 13 is lowered. Even in this state, although the electrical contact portion 19 is conductive, it is not energized and is in a warming standby state. Since the human body detection sensor 42 enters the warming operation only after detecting the human body, it is energy saving and economical.

  When the user is seated for defecation, the toilet seat heated to an appropriate temperature by the lamp heater 29 does not need to be heated further. On-off control (control that repeats until the energization amount is zero or the toilet seat temperature does not rise excessively) with low power. Thereby, even if the thermistor 41 or the like breaks down, the toilet seat temperature does not rise excessively during use, and it is safe. In addition to heating after detecting a human body as described above, the toilet seat 13 is heated for a very short time just before sitting on the toilet seat, further saving energy. If the lamp heater 29 is continuously energized for some reason, the cord-shaped temperature fuse 31 provided along the lamp heater 29 is blown above a predetermined temperature, and the lamp heater 29 is melted. Shut off the power to the. After the user has finished defecation, if the toilet seat has a local cleaning means (not shown), it is cleaned with warm water. By using the local cleaning means, the user can perform a comfortable defecation operation.

  Here, the seating detection means 38 has been described as being constituted by the microswitch 40 in the leg rubber 39, but it may be provided at the hinge portion of the toilet seat 13 provided so as to be rotatable, and there are various places and configurations. Can be considered.

  Further, as a means for heating the heating means 15, as described above, the method for automatically heating the toilet seat 13 using the human body detection sensor 42 has been described. However, after the user is seated, the user manually presses the switch to apply heat. There are also methods such as heating. In this case, in the state where the toilet seat 13 is lowered, the heater 13 is only turned on and is not energized, and is in a warming standby state. If the warming operation is performed for the first time by operating the switch, it is energy saving and economical in this case.

  Here, when the toilet seat 13 is lowered, it is electrically connected, so that the toilet seat 13 can be heated at any time by a switch operation or a human body detection sensor without being energized, or actually energized to perform a heating operation. When the toilet seat 13 is raised, the temperature rise is impossible and the toilet seat 13 cannot be heated when the toilet seat 13 is raised. As described above, as a means for switching between the temperature rise enable state and the impossible state in conjunction with the rotation of the toilet seat 13, the connector 16 is repeatedly contacted and non-contacted in conjunction with the rotation of the toilet seat 13 as described above. In addition to the method of realizing the switching, for example, when the heating means 15 is a so-called IH heater (electromagnetic induction heater) and the seating detection means 38 and the control means 43 are used to detect the seating of the user, the IH heater A method is also conceivable in which the toilet seat 13 is heated using electrical energy while being physically non-contact, such as turning on the power.

  In addition, as the detachable means that makes the toilet seat 13 removable from the support means 11, there is a method in which the detachable means 23 portion in FIG. 3 is formed of an elastic body and is movable so that it can be detached at the time of detachment. In this case, the rotation shaft 22 is disengaged from the rotation bearing 20 by the movement of the attaching / detaching means 23, and the toilet seat 13 is detached from the support means 11. In addition to this, the protruding portion of the rotating shaft 22 protrudes or retracts from the end surface of the toilet seat 13 by the slide mechanism, and this allows the detachment or a part of the rotating bearing 20 to be opened and closed. Various forms and means are conceivable, such as a method in which the rotating shaft 22 passes through the notched gap and is removable.

It can play a supplementary role in the heating. Further, when the seating of the user is detected without using the human body detecting means 42 and the toilet seat 13 is heated or by the switch operation of the user, the radiation-type heating element 24 is excellent and very short. Even if the temperature can be raised over time, it is economical because the input power is small by applying a small amount of power to the second heating elements 44 and 45 so as not to make the user feel cold at the moment of sitting. On the other hand, it can eliminate the cold feeling when sitting and is very effective.

  Both the code heater 44 and the surface heater 45 are inexpensive and can be realized with a simple configuration.

  On the other hand, when the radiation-type heating element 24 and the second heating elements 44 and 45 are used in combination, a different voltage may be applied to each heating element. In this case, the energizing terminal of the electrical contact portion 19 is a radiation-type heating element. By sharing the ground (earth) of the body 24 and the second heating elements 44 and 45, the number of terminals can be three.
