Further, in the description of the present embodiment, the same reference numerals are given to the same configurations and the effects and the same description is not repeated.

(Embodiment 1)
A heating toilet seat according to Embodiment 1 of the present invention will be described in the form of a heating toilet seat mounted on a toilet seat. FIG. 1 is a schematic configuration diagram of a cross-sectional view of the essential part, and FIG. 2 is a perspective view of a toilet device mounted with the heating toilet seat. 3 is a plan view of the heating toilet seat with a part cut away, FIG. 4 is a perspective view of a main part of a radiant heating element of the heating toilet seat, and FIG. 5 is a toilet seat case of the heating toilet seat. It is principal part sectional drawing.

  1 to 5, a heated toilet seat with a hot water washing function for washing an anus and a bidet after a stool has a horizontally long main body 21 attached to the rear end of the toilet 20 of the toilet device. A part of the warm water washing function is internally provided, and a ring-shaped toilet seat 22 and a toilet lid 23 mounted on the toilet 20 are rotatably provided.

  In addition, a human body detection sensor 24 for detecting the presence or absence of a human body in the toilet room by infrared rays and a seating detection sensor 25 for detecting the user's seating on the toilet seat 22 are incorporated in the sleeve portion of the main body 21. As shown in FIG. 1, the toilet seat 22 forms a toilet seat case 26 by welding and joining two upper and lower members made of synthetic resin at the inner and outer peripheral edges of each, and the inside of the toilet seat 22 is infiltrated with water or the like. It has the structure which has the airtight cavity part 27 which can prevent.

The ring-shaped toilet seat case 26 has an aluminum plate as a mirror surface facing a seat portion 28 corresponding to the upper surface of the toilet seat 22 on which a user using the toilet device sits in the left and right hollow portions 27 placed on the left and right sides of the toilet 20. The radiant energy reflecting plate 29 having a bent portion 29a that is finished and has the inner and outer end portions inclined upward, and the radiant energy reflecting plate 29 so that the radiant energy can be efficiently extracted to the seating portion 28. Two lamp heaters 30, which are radiation type heating elements that are located above and have a function of immediate warming (heating when heated to quickly generate heat), are provided in accordance with the shape of the toilet seat 22.

  Accordingly, the seating portion 28 of the toilet seat 22 is immediately warmed by receiving the light radiated radially by the lighting of the lamp heater 30. On the other hand, when the lamp heater 30 is immediately heated, the entire seating portion 28, that is, the location of the seating portion 28 that is the uppermost portion closest to the lamp heater 30, and the inner peripheral edge and the outer peripheral edge that are relatively far from the lamp heater 30. As shown in FIG. 4, a radiation energy suppression unit is provided so that the temperature of the seating unit 28 becomes uniform.

  That is, the radiant energy suppression part is applied or printed on the longitudinal surface of the lamp heater 30 that opposes the seating part 28, and the narrow heat-resistant paint 31 that reduces or blocks light and the thin heat-resistant paint 31 that transmits light without heat-resistant paint. The wide slits 32 are alternately provided. The radiant energy suppression unit increases the width of the heat-resistant paint 31 at a portion where the distance between the lamp heater 30 and the outer surface of the seating portion 28 (also referred to as the seating surface) is short (a portion directly above the lamp heater 30). The width of the heat-resistant paint 31 is narrowed and the width of the slit 32 is widened at a location where the distance between the lamp heater 30 and the seating surface is long, and the width of the slit 32 is increased. Thus, by increasing the passage of the amount of radiant energy that warms the seating surface, the temperature of the seating portion 28 as a whole is made uniform.

  In this embodiment, an example is shown in which two lamp heaters 30 are used. However, no matter how many lamp heaters 30 are used, there is no problem as long as the object of the present invention can be achieved.

  A thermostat 33 and a thermal fuse 34 that are electrically connected in series with the lamp heater 30 are provided in the vicinity of the lamp heater 30, and act to prevent overheating in the event of an unsafe situation. If the thermostat 33 and the thermal fuse 34 are provided so as to correspond to each of the two lamp heaters 30, the safety is further improved.

  The lamp heater 30 is configured by penetrating a filament 36 made of tungsten inside a glass tube 35 and enclosing a halogen gas 37, and repeats a halogen cycle reaction for forming tungsten halide as the filament 36 generates heat. Thus, the filament 36 is prevented from being consumed. By this action, the filament 36 having a very small heat capacity can be used as a heat source, and the temperature can rise rapidly.

  The lamp heater 30 is fixed to the radiant energy reflecting plate 29 by a lamp heater fixture 39 having a rubber bush 38 which is an elastic material, and the radiant energy reflecting plate 29 is fixed to a lower member of the toilet seat case 26 through rubber feet 40. Has been.

  FIG. 5 is a cross-sectional view of the main part of the upper member in the toilet seat case 26 of the heating toilet seat. The toilet seat case 26 constituting the toilet seat 22 is made of a transparent polypropylene resin material, and a radiant energy absorbing layer 43 containing a large amount of carbon black is formed on the upper surface of the case body 42, and further emitted from the lamp heater 30 thereon. The surface decorative layer 44, which is a light blocking layer in consideration of surface hardness, chemical resistance, gloss, etc., is formed.

The case body 42 of the toilet seat case 26 constituting the toilet seat 22 is formed of a transparent polypropylene resin material with an average thickness of 2.5 mm, so that the radiant heat transmittance is set to 70% or more, and the structure of the toilet seat 22 is rectangular due to its rigidity. It functions as a body. Further, the formed radiation heat absorption layer 43 has a thickness of 0.1 mm, and the surface decorative layer 44 has a thickness of 0.2 mm. Both layers receive the radiation energy (also referred to as radiation heat) of the light transmitted through the case body 42. Since it absorbs completely and is on the outer surface side of the seating portion 28 and has a very small heat capacity, it heats up instantaneously without conducting heat, thereby heating the seating portion 28 and simultaneously shielding the visible radiation.

  In addition, although the example which used the transparent polypropylene resin material was given for the toilet seat case 26, if it is transparent resin, such as a transparent polyethylene resin material, the objective of this invention can be achieved. Further, even if the surface decorative layer 44 does not block all visible light emitted from the lamp heater 30, the object of the present invention can be achieved.

  Further, the case body 42 of the toilet seat case 26 constituting the toilet seat 22 is provided with a thermistor 45 as a temperature detecting means in a recess opened on the inner surface thereof, so that the temperature in the vicinity of the radiation energy absorbing layer 43 can be detected. It has become. Since the thermistor 45 is provided corresponding to the seating portion 28 heated by the two lamp heaters 30, it is possible to perform fine temperature control for controlling each temperature separately, an abnormal temperature rise, and a lamp A stoppage of heat generation of the heater 30 can also be detected and can be appropriately handled.

  Further, the toilet seat 22 has an electrode 47 formed on the rotating shaft 46, and constitutes a toilet seat position detecting means 48 of the toilet seat 22 together with a bearing portion (not shown) of the main body 21, so that the toilet seat 22 is in an upright state or seated. Thus, it is detected whether the use position is in a substantially horizontal use position. The main body 21 takes in a detection signal from a room temperature thermistor 49 as a room temperature detection means to control the temperature of the lamp heater 30 and energizes the lamp heater 30 of the toilet seat 22 to start the temperature rise. There is provided a control unit 51 mainly composed of a microcomputer having a timer unit 50 for counting the number of times.

  Then, the control unit 51 takes in signals from the human body detection sensor 24, the seating detection sensor 25, and the toilet seat position detection means 48 to control the start and stop of energization of the lamp heater 30, and the signals from the thermistor 45 and the room temperature thermistor 49. The temperature of the lamp heater 30 can be controlled so that the temperature of the seating portion 28 that is taken in and becomes a warming surface becomes a predetermined temperature that is an appropriate temperature.

  About the heating toilet seat comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the user enters the toilet, the human body detection sensor 24 detects it and a detection signal is sent to the control unit 51. At this time, when it is confirmed by the signal from the toilet seat position detecting means 48 that the toilet seat 22 is in a substantially horizontal use position, the control unit 51 starts energizing the lamp heater 30.

  By this initial energization, the input energy is instantaneously converted to radiant energy, and is radiated from the filament 36 toward the case main body 42 through the glass tube 35, the radiant energy reflector 29, and the radiant energy suppression portion (heat resistant paint 31, slit 32). The The radiant energy of the lamp heater 30 is partly absorbed or reflected inside the case body 42 that is the upper member of the toilet seat case 22, but most of it is transmitted and the radiant energy absorbing layer 43 and the surface decorative layer 44 of the seating portion 28. Contributes to the temperature rise.

  Therefore, the lamp heater 30 starts to raise the temperature of the seating portion 28 after detecting that the user has entered the toilet room by the human body detection sensor 24, until the user lowers his clothes and sits on the seating portion 28. For example, the seating portion 28 can be instantaneously heated to an appropriate temperature in a few seconds. Therefore, it is possible to realize a very power-saving heating toilet seat that does not need to be energized at all times and keep the toilet seat 22 warm.

At this time, the radiant energy radiated from the lamp heater 30 is deflected by the bent portion 29 a of the radiant energy reflecting plate 29. Therefore, although it is the radiant energy reflecting plate 29 that efficiently extracts the radiant energy from the lamp heater 30 toward the seating portion 28, the radiation density of the outer peripheral edge portion and the inner peripheral edge portion of the seating portion 28 that is separated from the lamp heater 30 is obtained. Although it also acts to raise it and contributes to the uniformity of the radiant energy distribution to the upper part corresponding to the seating part 28 of the toilet seat case 26, it is basically insufficient.

  Therefore, in the present embodiment, a plurality of heat-resistant paints 31 and slits 32 having different narrow widths as the radiant energy suppressing portion are located immediately above the lamp heater 30 where the distance between the lamp heater 30 and the outer surface of the seating portion 28 is short. The width of the slit 32 is narrowed to reduce the amount of radiant energy for heating the outer surface of the seating portion 28, and the distance between the lamp heater 30 and the outer surface of the seating portion 28 is far from the left and right portions of the lamp heater 30. The width is increased to adjust the amount of radiant energy that reaches directly from the lamp heater 30 to the outer surface of the seat 28.

  In addition, although the example which applied the heat-resistant coating material 31 through the slit 32 as a radiation energy suppression part is shown, the same effect can be obtained by sticking aluminum tape or the like on the surface of the lamp heater 30 instead of the heat-resistant coating material 31. Can be obtained. In addition to the examples given here, the radiation radiated from the lamp heater 30 radiates from the outer surface of the seat 28 having a specific shape to the location directly above the lamp heater 30 and the locations of the inner and outer peripheral edges. There is no problem even if any one is used as long as it is possible to suppress the energy differently and make the temperature of the outer surface of the seating portion 28 uniform. That is, what is shown in FIGS. 6 to 9 can be considered.

  As shown in FIG. 6, the radiant energy suppression portion is provided with an aluminum plate 52 in a gap portion 27 corresponding to the gap between the lamp heater 30 and the seating portion 28 so as to cover a part of the upper surface of the lamp heater 30. . As a result, the radiant energy radiated from the lamp heater 30 is blocked by the aluminum plate 52 at the position of the seating portion 28 that is directly above the lamp heater 30, and becomes radiant energy via the aluminum plate 52. It is possible to suppress the temperature rise, and the radiant energy directly radiated at the inner and outer peripheral edges of the seating portion 28 far from the lamp heater 30 increases the temperature, and the temperature of the outer surface of the seating portion 28 as a whole increases. Uniformity can be realized. Although an example using the aluminum plate 52 is shown here, there is no problem even if a stainless plate, another metal, or a synthetic resin plate is used.

  Further, as shown in FIG. 7, the radiant energy suppression portion increases the thickness of the synthetic resin material constituting the toilet seat case 26 at a position directly above the lamp heater 30 of the toilet seat case 26. In this case, the low radiant energy transmission portion 53 is provided. Therefore, the radiation energy radiated from the lamp heater 30 is reduced in the radiation energy transmittance by the radiation energy low transmission portion 53 at the position of the seating portion 28 which is directly above the lamp heater 30, and becomes low radiation energy. The temperature rise can be suppressed, and at the inner and outer peripheral edges of the seating portion 28 far from the lamp heater 30, the thickness of the synthetic resin of the toilet seat case 26 is increased so that the transmission of radiant energy becomes normal and the temperature rises. Uniform temperature on the outer surface of the seat 28 as a whole can be realized.

  Further, as shown in FIG. 8, the radiant energy suppression unit changes the material of the radiant energy absorption layer 43 to a position of the radiant energy absorption layer 43 corresponding to the portion immediately above the lamp heater 30 of the toilet seat case 26. Further, it is configured by providing a low radiation energy absorbing portion 54. Therefore, the radiant energy radiated from the lamp heater 30 is reduced by the low radiant energy absorption portion 54 at the seating portion 28 located immediately above the lamp heater 30 and the radiant energy is lowered. The temperature rise can be suppressed, and the radiant energy absorbing layer 43 is provided at the inner and outer peripheral edges of the seating portion 28 farther than the lamp heater 30, so that the absorption of the radiant energy becomes normal and the temperature rises. Uniform temperature on the outer surface of the portion 28 can be realized.

Further, as shown in FIG. 9, the radiant energy suppression unit is disposed at the position of the radiant energy absorption layer 43 corresponding to the portion immediately above the lamp heater 30 of the toilet seat case 26.
Is provided by providing a multi-heat capacity portion 55 having a large thickness. Therefore, the radiant energy radiated from the lamp heater 30 increases the heat capacity of the radiant energy absorption layer 43 by the multi-heat capacity part 55 at the position of the seating part 28 directly above the lamp heater 30, and delays the temperature rising rate.
The inner and outer peripheral edges of the seating portion 28 farther from the lamp heater 30 have normal temperature rise speeds, and the temperature uniformity on the outer surface of the seating portion 28 as a whole can be realized.

  The control unit 51 calculates from the temperature difference between them and the respective temperatures based on the signals of the thermistor 45 and the room temperature thermistor 49 at the start of energization, and the energization limit time for initial energization that is set and stored in advance. When the elapsed time counted by the timer unit 50 reaches the energization limit time, the energization amount is reduced or zero, and then the seating portion 28 of the toilet seat 22 is set to an appropriate temperature based on a signal from the thermistor 45. The energization amount is controlled so that

  As a result, the thermistor 45 detects the temperature in the vicinity of the seating portion 28 that is actually touched by the user, and the control unit 51 accurately raises and maintains the temperature to an appropriate temperature, so that the toilet seat 22 is comfortable to use. Since the amount of radiant energy input is controlled in accordance with the amount of load based on the signal from the thermistor 49, it can be heated to an appropriate temperature with higher accuracy and safety.

  On the other hand, when the toilet seat 22 is in a standing state or when a male user holds the toilet seat 22 in a standing state for small use after entering the room, the control unit 51 uses the signal from the toilet seat position detecting means 48 to The energization to the lamp heater 30 is stopped. Accordingly, it is possible to reduce the wasteful heating of the toilet seat 22 and to save energy, and it is possible to prevent the filament 36 from being disconnected due to gravity in the length direction which is the tension direction of the filament 36.

  Further, even if the user opens and closes the toilet seat 22 in a standing state and a substantially horizontal state according to the purpose, in addition to the impact damping effect of the lamp heater fixture 39 having the rubber bush 38 which is an elastic material, the rubber feet 40 Due to the effect, the impact on the lamp heater 30 is absorbed, and the glass tube 35 and the filament 36 can be prevented from being damaged.

  Next, when the user is seated for defecation, the output range in which the halogen cycle is effective as described above until the energization amount to the lamp heater 30 is zero or the toilet seat temperature does not rise excessively by the signal of the seating detection sensor 25. Control by changing the energization cycle. Thus, the toilet seat temperature does not rise during use, and there is no worry of causing burns or the like, and the user can use it comfortably.

  In general, since the heated toilet seat is seated with the skin in direct contact with the toilet seat 22 with a built-in heater, sufficient consideration is required for safety. Although it can be used safely and comfortably as described above in a normal use state, in the unlikely event that a microcomputer (not shown) malfunctions for some reason and the lamp heater 30 is continuously energized, etc. It is necessary to operate safely. In the present embodiment, a thermostat 33 is used to realize this.

  In the above-described embodiment, the lamp heater 30 is described as being provided with a pair of left and right, but is not limited thereto. Moreover, although the radiation energy absorption layer 43 and the surface decorative layer 44 are configured to completely shield light and radiation emitted from the lamp heater 30, some or most of them may be intentionally transmitted.

(Embodiment 2)
FIG. 10 is a partially cutaway plan view of a heated toilet seat with a hot water cleaning function according to Embodiment 2 of the present invention. The present embodiment is different from the first embodiment shown in FIGS. 1 to 5 in that heating by the lamp heater 30 is performed due to the design of the toilet seat 22 because there is no space for the lamp heater 30. A cord-like heater 56 is arranged in a meandering manner in the cavity 27 on the back surface of the seating portion 28 at a portion that is difficult to perform or at the rear portion between the left and right seating portions 28 that do not need to be heated immediately. A provided second heating element is installed.

  In addition, in FIG. 10, although the 2nd heat generating body is provided in the back part of the toilet seat 22, it is not restricted to this. In addition, although the second heating element has been described as a cord-shaped heater, the present invention is not limited to this, and a heater formed by patterning a metal to have a flat shape, a heater having PTC characteristics, or the like can also be used.

  About the toilet apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The heater 56 as the second heating element is electrically connected in parallel with the lamp heater 30 and has signals from the thermistor 45 and the room temperature thermistor 49 provided on the back surface of the seating portion 28 on which the second heating element is provided. At the same time, the controller 51 controls the temperature of the seating portion 28 so as to be an appropriate temperature.

  And since the 2nd heat generating body heats the part which is hard to be heated with the lamp heater 30, a heating toilet seat can be used comfortably. The second heating element is always energized to warm the toilet seat surface by heat conduction. However, since the second heating element is provided only in a part of the seating portion 28, the power consumption does not increase significantly.

  As described above, by providing a plurality of lamp heaters 30, there is no risk of damage against distortion and impact applied to the toilet seat 22, and it is safe, and a non-heated portion generated by dividing the lamp heater 30 is the first. By heating with two heating elements, a heated toilet seat that provides a comfortable feeling of heating can be obtained.

  As described above, since the heating device of the present invention can provide a uniform surface temperature of the seating portion by providing the radiant energy suppression portion, a heating device that can be used safely can be obtained. It can be applied as a heating technique for toilet seats, chairs, and the like, which are sitting devices.
