  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
Figure 1 is a view to oblique plan view of the state in which the heating seat attached to the toilet bowl in the first embodiment of the present invention, FIG. 2, FIG. 3 is a seat in each seat in a state in which removal of the seat from the toilet It is a figure which shows a connector, and a figure which shows the support means side connector in a support means. FIG. 4 is a plan view of the toilet seat.

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 12 is provided with a toilet seat cover that covers the front surface of the toilet 12 and the toilet seat 13 by moving up and down like the toilet seat 13, but the illustration is omitted. Seat 13 in FIG. 2 is a seat-side connector 19 having electrical terminals 1 8a for supplying electricity to the heating unit 15, connected for Keru Installing ensure seat side connector 1 9 the support means connector (described later) Rotating means 21 is provided that enables the toilet seat 13 to be rotated while the means 20 and the electrical terminal 18a are connected. In FIG. 3, the support means 11 includes a support means-side connector 22 having an electric terminal 18 b for supplying electricity to the heating means 15 of the toilet seat 13 and a connection means 20.

  In FIG. 4, the toilet seat 13 is for attaching to the toilet seat side connector 19 having an electrical terminal 18 a for receiving supply of electricity from the support means 11 to the heating means 15, and for the toilet seat 13 itself to rotate. And a detaching means 23 for detaching the toilet seat 13 from the support means 11. In FIG. 4, the toilet seat side connector 19 is provided on one rotating shaft 26.

  In FIG. 5, the toilet seat 13 includes a radiant heating element 24 as heating means. FIG. 6 is a main cross-sectional view of the toilet seat 13. In the cavity 27, a radiation reflector 28 having a mirror-finished aluminum plate facing the seat 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 13 a of the toilet seat 13 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.

  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 to the toilet 12 so as to be fixed, 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 attached to the support means 11, the toilet seat side connector 19 provided on the toilet seat 13 for supplying power to the heating means 15 and the support means side connector 22 provided on the support means are fitted together. Then, the electrical terminals 18a and 18b are connected to each other, whereby the power supplied to the support means 11 is supplied to the heating means 15 provided in the toilet seat 13, and the heating means 15 functions. After the connector is connected, even if the toilet seat 13 rotates, the toilet seat 13 freely rotates while the electrical terminals 18a and 18b are connected by the rotating means 21. At this time, since the connector is securely connected by the connecting means 20, even if the rotating means 21 does not function as intended, an excessive force is not applied to the electric terminals 18a and 18b, and the toilet seat 13 is rotated during energization. It is safe to let it go. Specific examples of the configuration of the rotating means 21 include a method of using a bearing and a double combination of a cylindrical tube on the outside and the inside. In addition, the heating means 1 provided in the toilet seat 13 from the toilet seat side connector 19 is used.
About the electric cord connected to 5, the reliability in energization becomes still higher by devising so that this may not be twisted by rotation of the toilet seat 13.

  FIG. 7A shows the shape of the connector portion with three electrical terminals, and FIG. 7B shows the shape of the connector with two electrical terminals. As shown to (a), when the front-end | tip of the electric terminal 18a is rounded shape, when connecting the toilet seat side connector 19 and the support means side connector 22, it will become possible to connect easily. Further, as shown in FIG. 8, if the shape of the electrical terminal 18b of the support means side connector 22 is such that the cross-sectional area of the entrance portion is large and the back side is small, it is easy to connect when connecting the connector. Here, regarding the male and female of the electric terminals 18a and 18b, the toilet seat side, the support means side, and the case of the present embodiment may be opposite to each other, and the above is also true in the opposite case.

  Since the toilet seat side connector 19 and the support means side connector 22 are provided on the rotation shaft 26 that is the rotation center axis of the toilet seat 13, foreign matters such as urine that the boy urinates while standing are placed on the connector and the electrical terminal 18. There is no such thing.

  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, the human body detection sensor 42 detects this, 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. As described above, if the radiant heating element 24 is used, the warming surface of the seating portion 25 of the toilet seat 13 can be heated almost instantaneously, so that energy is saved without energizing the heater at all times. 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. Thus, since the human body detection sensor 42 starts the heating operation only after detecting the human body, it is energy saving and economical.

  When the user is seated for defecation, the amount of power supplied to the lamp heater 29 is controlled by the signal from the seating detection means 38 until the toilet seat temperature does not rise excessively. Thereby, even if the thermistor 41 or the like breaks down, the toilet seat temperature does not rise during use, and it is safe without fear of causing burns. 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. 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. 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.

  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 described above, the method of heating the toilet seat 13 automatically using the human body detection sensor 42 as a means for heating the heating means 15 has been described. However, after the user is seated, the user manually presses the switch. There are also methods such as heating. Also in this case, if the heating operation is performed for the first time by operating the switch, it is energy saving and economical.

  In addition, as the detachable means for making the toilet seat 13 detachable from the support means 11, the detachable means 23 portion in FIG. Various forms and means are conceivable, such as a method in which the protruding portion of the moving shaft 26 is easily pulled out and retracted by the slide mechanism and can be detached by being retracted. Here, for example, in order to detach the toilet seat 13, the position where the toilet seat 13 can be attached / detached, which cannot be attached / detached unless the toilet seat 13 is raised, is structurally devised and the rotating means 21 is rotatable. However, when the toilet seat 13 is removed from the support means 11 and the toilet seat 13 is cleaned, the electrical terminal 18 is attached to the support means 11 again after being removed. -Since it is at an angle, the connector can be easily connected. As a specific configuration in which the rotating means 21 can rotate but does not rotate easily, a cylindrical tube is double-combined between the outside and the inside, and the fit between the inside tube and the outside tube is started from an intermediate fit. For example, it is possible to use a method of finishing by combining tolerances between tight fits.

  When the radiant heating element 24 is used and the toilet seat is heated immediately, a relatively large current flows in the circuit in a short time. Even in such a case, if the connector provided with the rotation means 21 is used, the contact portion that electrically connects the toilet seat 13 while allowing the toilet seat 13 to rotate is not generated, but the contact portion depends on the rotation state of the toilet seat until then. Since there is no possibility of failure in the conduction state, large current can be stably energized. Therefore, stable heating is possible even with a heated toilet seat using heating means such as the radiant heating element 24.

  In the present embodiment, two radiation-type heating elements 24 are provided on the left and right sides of the toilet seat, respectively. However, when one heating element is provided along the shape of the toilet seat, It is also possible to take the following configuration. Conventionally, there has been a configuration of an electrical contact portion that is coaxial cable-shaped, the cable itself is freely rotatable, and slides as the toilet seat is rotated. As shown in FIG. 7B, the toilet seat side connector 119 has two electrical terminals 118a, and is provided with rotating means 121 such as a bearing around the toilet seat side connector 119. The electric terminal 118a serving as an electrical contact portion is configured to be free of sliding with the rotation while being freely rotatable. The connecting means 120 is provided at two locations around the terminal with the polarity of the connecting portion being large, so that the connection of the two electrical terminals is always constant when the toilet seat is attached and detached. By adopting such a configuration, the toilet seat can be rotated and detached, and the electrical contact portion can be kept in a stable conductive state.

  In addition, when a relatively large current flows, the plurality of electrical terminals may need to be provided with a certain distance from each other. In such a case, it is easy to embed an insulating member between the terminals such as the electrical terminals 18a and 118a, or to increase the shape of the connector so that the distance is increased. It is also possible to respond.

These second heating elements are used together with the radiant heating element 24, for example, the portion on the support means 11 side of the toilet seat 13 that is difficult to construct with the radiant heating element 24, that is, the rear part of the human body when seated. It can play a supplementary role in the heating. Further, without using the human body detecting means 42, Ri warmed toilet seat 13 by detecting the seated user, such as when warming by the switch operation of a user, even if radiant heating elements 24 Gago rather short time be capable of raising the temperature in, cormorants I does not feel the cold to the user at the moment of being seated, a small power by leaving heated always guarantee given to the second heating element 44 and 45, a small input power Therefore, while being economical, it can eliminate the feeling of cold and cold at the time of sitting and is very effective.

  Further, when heating is performed by the radiant heating element 24, if temperature unevenness occurs in the toilet seat 13, the temperature unevenness can be eliminated by using the second heating elements 44 and 45 together.

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

On the other hand, the radiant heating elements 24 in combination a second heating element 44 and 45, may not Banara Kere such added a different voltage to each heating element, in this case, the electric terminal 18 and the radiation heating elements 24 By making each ground (earth) of the second heating elements 44 and 45 common, it is possible to realize three terminals.
