Is equipped with a part of the hot water washing function, and is provided so as to be rotatable so that the ring-shaped toilet seat 23 and the toilet lid 24 mounted on the toilet bowl 21 can be opened and closed in a horizontal state. When not in use, the toilet lid 24 is laid sideways so as to cover the seating portion 25 which is a warming portion on the upper surface of the toilet seat 23. In addition, an infrared sensor 26 that detects whether a human body has entered the toilet room is incorporated in the sleeve portion of the main body 22.

  In FIG. 1, the toilet seat 23 is formed by joining two members, a synthetic resin toilet seat top 23a and a toilet seat base 23b, with a concave-convex fitting of the inner and outer peripheral edges of each, and a cavity 27 is formed in the interior. It has a structure. On the toilet seat top 23a, a seating portion 25 is formed as a portion on which a user who uses the toilet device 20 sits.

  The hollow portion 27 is opposite to the seating portion 25 and has a radiation reflecting plate 28 having an elastic force obtained by mirror-finishing an aluminum plate, and left and right lamp heaters 29 that are radiation heating elements on both sides of the seating portion 25. Lamp heaters 29a and 29b are provided in conformity with the shape of the toilet seat 23 through a predetermined space from the inner surface of the seat portion 25. That is, the lamp heaters 29a and 29b (hereinafter, indicated by reference numeral 29 when the lamp heaters 29a and 29b do not need to be specified) are seated on the toilet seat 23 that is ring-shaped in a plan view of the toilet seat 23 as shown in FIG. The left and right seats 25a and 25b, which are parts 25, are provided along the shape of the toilet seat 23.

  The left and right seating portions 25a and 25b, which are the seating portions 25, are portions where the thighs come into contact when a person is seated. As shown in FIG. 1, the radiation reflector 28 has a bent portion 28 a upward (at the seating portion 25 side) on the entire circumference of the inner and outer ends thereof, and the radiation energy from the lamp heater 29 is deflected, A device for making the radiation distribution to the seating portion 25 uniform has been devised.

The thermostats 30a and 30b and the thermal fuses 31a and 31b are provided so as to correspond to the two lamp heaters 29a and 29b, respectively, and safety is improved.

  The lamp heater 29 is configured by penetrating a filament 33 made of tungsten inside a circular quartz glass tube 32 and enclosing a halogen gas, and welding and sealing the quartz glass tube 32 at both ends. By repeating the halogen cycle reaction for forming tungsten halide with heat generation, the filament 33 is prevented from being consumed. By this action, the filament 33 having a very small heat capacity can be used as a heat source, and the radiation energy can be caused to rise very steeply.

  Therefore, the lamp heater 29 can quickly raise the seating portion 25 of the toilet seat 23 to an appropriate temperature within a few seconds until the user enters the toilet room, lowers his clothes, and sits on the seating portion 25 of the toilet seat 23. Therefore, a power-saving heating element that does not need to be energized at all times and warm the toilet seat 23 is obtained.

  Further, as shown in FIG. 4 which is a cross-sectional view taken along line AA of FIG. 3, the lamp heater 29 has a holding portion 35 in the vicinity of both ends, which is a flat sealing portion 34 formed by sealing both ends. The radiation reflector 28 is fixed to the toilet seat base 23b by rubber feet 36 which are electrical insulators. As shown in FIG. 5, the holding portion 35 is provided with a rectangular cutout portion 37 along the longitudinal direction of the lamp heater 29 of the radiation reflecting plate 28, and the seating portion is located above one end portion of the cutout portion 37. By bending (cutting and raising) at a right angle toward the portion 25 side, it is formed integrally with the radiation reflector 28 to provide a robust structure.

  A pair of left and right side columns 35a is left in the lower part of the holding unit 35, and a kerf 35b is formed between the lower part of the column 35a, and a space 35c is formed in the center to form a pair A first cut-and-raised portion 38 is provided, and the placement portion 39 is formed by bending the first cut-and-raised portion 38 in the longitudinal direction of the lamp heater 29, and the sealing portions 34 formed at both ends of the lamp heater 29. Is placed. The mounting portion 39 is formed so that the distance between the lamp heater 29 and the radiation reflector 28 is substantially equal.

  In addition, a second cut and raised portion 40 is provided on the upper portion of the holding portion 35 so as to face the lower space 35c in the center via a space 35d between the left and right support columns 35a. 40 is bent in the longitudinal direction of the lamp heater 29, and a clamping part 41 is provided to sandwich the sealing part 34 of the lamp heater 29 with the lower mounting part 39 by an elastic force, and the base part with one column part 35a is provided. 35e, and when guiding the sealing portion 34 of the lamp heater 29 between the mounting portion 39 and the clamping portion 41, the structure is twisted in the direction of the arrow about the other support portion 35a. Therefore, the lamp heater 29 is elastic after the clamping part 41 is twisted in the direction of the arrow around the other support part 35a of the holding part 35 and the sealing part 34 of the lamp heater 29 is placed on the mounting part 39. The clamping part 41 is returned to its original position by force, and the sealing part 34 is fixed to the mounting part 39.

  Further, the tip of the mounting portion 39 of the holding portion 35 is bent toward the radiation reflecting plate 28 that is downward from the horizontal, and the tip of the holding portion 41 is bent toward the seating portion 25 that is upward from the horizontal. 42b are formed so as to receive both ends of the lamp heater 29 when they are displaced. Immediately below the lamp heater 29 is provided a buffer 43 formed by cutting and raising the radiation reflector 28 in the longitudinal direction of the lamp heater 29. 44 is a lead wire of the lamp heater 29, and 45 is a terminal for connecting the lead wire 44 and the filament 33.

  As shown in FIG. 6 (B-B cross section in FIG. 3), the thermostat 30 is connected in series to the lamp heater 29 (not shown), and is provided facing the lamp heater 29, and the radiation reflector 28. Is fixed to a fixing portion 47 formed by bending upward a third notch 46.

  As shown in FIG. 7, the seating portion 25 is provided with a surface layer 49 that is a film material on the outer surface of a transmission body 48 that is formed by injection molding using a transparent polypropylene resin material, and the transmission body 48 and the surface layer 49. A radiant energy absorbing layer 50 containing a large amount of a radiant energy absorber mainly composed of a black pigment such as carbon black is formed therebetween. The surface layer 49 shields visible light emitted from the lamp heaters 29a and 29b and has a hue that matches the color tone of the entire toilet seat 23 in consideration of surface hardness, chemical resistance, gloss, and the like, and is monochromatic. Not limited to this, a combination of a plurality of colors or a designed pattern may be used.

  The seating portion 25 is pre-molded into a shape of the toilet seat top 23a by vacuum molding or the like after preliminarily molding the surface layer 49 on which the radiation energy absorbing layer 50 has been printed, and then mounted on a mold for molding the toilet seat top 23a. A transparent polyester resin or acrylic resin can also be used as the transparent body 38.

  The seating part 25 transmits about 70% of the radiant energy by molding the transparent polypropylene resin material that is the transmission body 48 with an average thickness of 2.5 mm. The total thickness of the radiant energy absorbing layer 50 and the surface layer 49 is about 0.2 to 0.5 mm in total, and both these layers absorb the radiant energy transmitted through the transmissive body 48 and have a very small heat capacity, so that they rise instantaneously. Simultaneously with the heating, visible light is shielded and the surface of the seating portion 25 is heated.

  As shown in FIG. 1, the seating portion 25 is provided with a thermistor 51 as temperature detecting means in a recess opened in the inner surface thereof, so that the temperature in the vicinity of the radiation energy absorbing layer 50 can be detected. That is, by providing the thermistor 51 in the vicinity of the surface of the seating part 25 heated by the two lamp heaters 29a and 29b, a signal from the thermistor 51 is taken into the control part 52 and the temperature of the seating part 25 is an appropriate temperature. Energization control to the lamp heater 29 is performed so that the temperature is reached. Therefore, fine temperature control of the seating portion 25 is possible, and an abnormal temperature rise or a heat generation stop due to disconnection can be detected and appropriately dealt with.

  The toilet apparatus will be described below before describing the operation and action of the lamp heater holding structure of the present invention. In the above embodiment, when the power is turned on, the toilet device 20 becomes usable, and when the user enters the toilet, the infrared sensor 26 detects that, and the signal is sent to the control unit 52, and the lamp Energization of the heater 29 is started. By this initial energization, the input energy is instantaneously converted into radiant energy and radiated from the filament 33 toward the seating portion 25 through the quartz glass tube 32 and the radiation reflector 28.

  Further, the radiant energy is partially absorbed or reflected inside the transmissive body 48 of the seating portion 25, but most of it is transmitted and contributes to the temperature rise of the radiant energy absorbing layer 50 and the surface layer 49. Accordingly, the lamp heater 29 is energized when the user enters the toilet, and the seat 25 of the toilet seat 23 can be heated in a very short time. Become a heating element. The seating portion 25 uses, for example, a lamp heater with a power density of 1 W / mm, and when the distance from the lamp heater 29 to the lower surface of the seating portion 25 is 20 mm, when the room temperature is 15 ° C., it does not feel cold in about 4 seconds. It is possible to raise the temperature (27 to 28 ° C.) and to heat the seating section 25 until the person is seated on the seating section 25 by detecting that the person has entered the toilet with the infrared sensor 26. Is possible.

  Thereby, the thermistor 51 detects the temperature in the vicinity of the seating portion 25 that is actually touched by the user, and the control unit 52 accurately raises and maintains the temperature to an appropriate temperature, so that the use of the toilet seat 23 is comfortable. Since the amount of radiant energy input is controlled according to the amount of load based on the above, it can be heated to an appropriate temperature with higher accuracy and safety.

  In addition, since the initial energization time control is preferentially performed, the energization amount is reduced and the temperature increase rate is reduced after the energization limit time, so that the toilet seat 23 can be heated safely even if the response speed of the temperature detection means is slow. In addition, an inexpensive temperature detecting means can be used.

  Next, when the user is seated for defecation, the amount of energization to the lamp heaters 29a and 29b is controlled by the signal from the seating detection means 36 so that the toilet seat temperature does not rise excessively. Thus, the toilet seat temperature does not rise excessively during use, and it is safe without fear of causing burns or the like.

  In particular, in the lamp heater holding structure of the present invention, the holding part 35 and the fixing part 47 are configured as shown in FIGS. First, since the holding portion 35 and the fixing portion 47 are integrally formed by cutting and raising the notch portion 37 from the radiation reflecting plate 28, the positional relationship between the radiation reflecting plate 28 and the radiation type heating element 29 is kept constant. In addition, it is not necessary to attach separate members to each other, and it can be configured inexpensively in the manufacturing process.

  Further, the holding portion 35 of the radiation reflecting plate 28 is formed by cutting and raising the notch portion 37 toward the lamp heater 29 along the longitudinal direction of the lamp heater 29, so that the portion directly below the heat generating portion of the lamp heater 29 is formed. Since the radiation energy is reflected without reducing the reflection area of the radiation reflector 28, the seating portion 25 can be heated uniformly.

  Further, a pair of first cut-and-raised portions 38 are provided at the lower portion of the holding portion 35, and the first cut-and-raised portions 38 are bent to constitute a placement portion 39 on which the lamp heater 29 is placed. The portion can be formed in a planar shape, stress is not concentrated on a part of the lamp heater, and damage to the lamp heater can be prevented.

  Further, the mounting portion 39 is configured to mount the sealing portions 34 formed at both ends of the lamp heater 29 so that the flat portion of the sealing portion 34 is held by the flat portion of the mounting portion 39. Therefore, the effect of avoiding stress concentration on a part of the lamp heater 29 and preventing the lamp heater 29 from being damaged increases.

  Further, the second cut and raised portion 40 is provided on the upper portion of the holding portion 35, the second cut and raised portion 40 is bent to form the holding portion 41, and the upper surface of the sealing portion 34 of the lamp heater 29 is pressed down. Since both sides of the sealing portion 34 are held by the mounting portion 39 and the holding portion 41, the sealing portion 34 is securely held, and stress concentration on a part of the lamp heater 29 is avoided to further prevent the radiation-type heating element 29 from being damaged. It is valid.

  Further, the inclined portion 42a, 42b is formed so that the front end portion of the mounting portion 39 faces downward from the horizontal and the front end portion of the holding portion 41 faces upward from the horizontal. Even when the opening / closing operation is performed, the heat generating portion of the lamp heater 29 is received by the inclined portions 42a and 42b and does not directly contact the respective tips of the mounting portion 39 and the holding portion 41, and a part of the radiant heating element. Therefore, the lamp heater 29 can be prevented from being damaged.

  That is, as shown in FIGS. 8A and 8B, from the state of FIG. 8A in which the toilet seat 23 is held horizontally in a normal state, for example, as shown in FIG. When the toilet seat 23 is in a state of being flipped up, such as during a urination, if the inclined portions 42a and 42b are provided, as shown in the frame C of FIG. Since the tip of 41 does not directly contact the quartz glass tube 32 of the lamp heater 29 and acts like a leaf spring to relieve stress, the risk of breakage can be avoided. On the other hand, when there are no inclined portions 42a and 42b as shown in FIG. 9A, the tips of the mounting portion 39 and the holding portion 41 are connected to the lamp heater as shown in the frame D of FIG. 9B. If the toilet seat 23 is opened and closed roughly, there is a high risk of damage to the quartz glass tube.

  Further, by cutting and raising the radiation reflector 28 directly below the lamp heater 29 to form the buffer portion 43, shocks such as when the toilet seat 23 is opened and closed are alleviated by the action of the spring of the buffer portion 43. Even in this case, the shock absorber 43 receives the shaking of the lamp heater 29 and can prevent the lamp heater 29 from being damaged.

  The holding portion 35 can be formed at an intermediate position in the longitudinal direction of the lamp heater 29. In this case, the holding portion 35 is formed by cutting and raising a notch portion 37 provided in the radiation reflecting plate 28. Therefore, since the notch portion 37 has no reflection effect, it is desirable to make the notch portion 37 as small as possible.

  Furthermore, since the mounting portion 39 is formed so that the distance between the lamp heater 29 and the radiation reflector 28 is substantially equal, the radiant energy from the lamp heater 29 is evenly reflected to make the seat portion 25. Therefore, the temperature variation of the seating portion 25 can be reduced.

  In the above embodiment, the sealing portions positioned at both ends of the radiation-type heating element are supported by the mounting portions of the holding portion. It may support the middle of the body.

  As described above, the heating device of the present invention and the toilet device equipped with the same in the toilet seat can be heated instantly and comfortably, and the radiant heating element can be securely held, so that the seat is seated. It can be applied as a heating technique for devices, such as hands, waist, abdomen, and soles where human bodies come into contact.
