Description

[Detailed description of the invention] This invention relates to an electric heated toilet seat that is attached to a Western-style toilet bowl and heats the buttocks during defecation, thereby preventing damage to the equipment in the event of an abnormality and improving safety for the human body. The purpose is to

Conventionally, this type of electrically heated toilet seat has a toilet seat body 2 with a built-in heater 1 and a "strong" seat as shown in Figures 1 and 2.
It consisted of a capacity selector switch 4, which turned on full-wave energization when in "weak" mode, turned on half-wave energization through a diode 3, and reduced the amount of heat generated by the heater to about half that of "strong" mode. Also, inside the toilet seat main body 2, there is a safety device 5 connected in series to the heater 1 when the electricity is on.
When the temperature of the heater 1 rises abnormally, the protector 5 operates to stop the power supply to the heater 1.

In this configuration, the heater 1 has a saturation specification, and the surface temperature of the toilet seat body 2 is determined by the ambient temperature, and as the ambient temperature increases or decreases, the surface temperature also increases or decreases. Therefore, when a person with a body temperature of about 37°C sits on the toilet seat body 2, the temperature of the contact surface between the buttocks and the toilet seat body 2 is determined by the heat generated by the heater 1, the human body temperature, and the buttocks and the toilet seat body 2. This temperature rises due to the close heat retention of the product, which is not only extremely inconvenient to use, but also causes low-temperature burns when used by people with paralyzed temperature sensation in their buttocks, such as physically disabled people. .

Additionally, toilet seats are often covered with covers to make the surface feel nicer to the touch.
In the conventional type, the temperature of the toilet seat body 2 rises significantly due to the heat retention properties of the cover, and the safety device 5 immediately activates, making it inconvenient to use, or if the safety device 5 does not operate, the toilet seat body 2 This may cause discoloration, deformation, and damage. Further, since there is only one protector 5, the range in which temperature rise can be detected is narrow, and if a portion of the toilet seat body 2 is covered with a cloth, the heater in that portion heats up locally and deformation of the toilet seat body 2 is unavoidable.

The present invention has been devised to eliminate the above-mentioned conventional drawbacks, and its configuration will be explained based on the drawings. FIG. 3 is an external view of a toilet seat showing an embodiment of the present invention, and FIG. 4 is a schematic sectional view seen from the back side of FIG. 3. The toilet seat main body 6 and the lid 7 are rotatably attached to a controller case 8, and the controller case 8 is configured to be fixed to a toilet bowl 9 with mounting bolts (not shown). As shown in Fig. 4, the toilet seat body 6 is approximately o-shaped, with the axis of symmetry 1
It is almost symmetrical with respect to 0. Furthermore, on the inner surface of the toilet seat body 6, an electric heater 11 is arranged and fixed on almost the entire surface of the part corresponding to the part on which the user rests his buttocks. A temperature detection element 12 is fixed on the heater 11, and a protector 13 is provided on or near the electric heater 11 on the right side of the axis of symmetry 10.

The positions of the temperature detection element 12 and the protector 13 are as follows:
The temperature detection element 12 and the protector 13 may not be located on the same side with respect to the axis of symmetry 10. In addition, the temperature detection element 12 and the protector 1
As shown in FIG. 4, numeral 3 is located approximately in the middle of the left and right sides of the toilet seat body 6 in the direction of the axis of symmetry 10, and is provided on the left side of the toilet seat body 6 in the left and right lateral directions. The protector 13 is electrically connected in series with the electric heater 11. The temperature detection element 12 and the electric heater 11 are electrically guided into the controller case 8 by a connection cord 14 and connected to a temperature control device 15. Temperature control device 15
In accordance with the resistance change of the temperature detection element 12, the amount of current to the electric heater 11 is controlled so as to keep the surface temperature of the toilet seat body 6 constant.

FIG. 6 shows the pressure distribution applied to the toilet seat body 6 when the user 16 rests his or her buttocks on the toilet seat body 6, and shows the distribution of pressure applied to the toilet seat body 6 at approximately central portions 17, 18 of the length in the direction of the symmetry axis 10. It shows the maximum pressure in the vicinity. These central portions 17 and 18 have good adhesion between the buttocks and the toilet seat main body 6, and due to the heat retention effect and human body temperature, the temperature is maximized.

With the configuration of the present invention, the temperature detection element 12 or the protector 13 is installed both inside the center parts 17 and 18.
Because of the location of the toilet seat, the maximum temperature is controlled at a constant level, and even when the user sits on the toilet seat body 6, the surface temperature does not rise, and comfortable heating can be obtained at all times. It will not cause low-temperature burns even if used by people who have paralyzed temperature sensation in their buttocks. In addition, in the unlikely event that the opening/closing impact force of the toilet seat body 6 or the static load loading force of the human body causes the temperature detection element 1 to
Even if an abnormality occurs in the toilet seat 2 or the temperature control device 15, the safety device 13 located at the maximum temperature part operates promptly, and there is no risk of burns or discoloration or deformation of the toilet seat body 6 due to high temperature. Moreover, even if the surface of the toilet seat is covered, discoloration and deformation can be prevented by the functions of the temperature detection element 12 and the temperature control device 15. In addition, since the temperature detection element 12 and the protector 13 are provided separately on the left and right sides of the axis of symmetry 10 of the toilet seat body 6, the range for sensing temperature rise is widened. Even if the toilet seat body 6 is covered, the temperature detection element 12 or the safety device 13 will be activated.
Deformation can be prevented by heat. Further, the temperature detection element 12 and the safety device 13 are located on the left side in the lateral direction away from the left and right center portions 17 and 18 of the toilet seat body 6, which is subject to the maximum pressure and the largest amount of distortion when the user is seated. Therefore, the temperature detection element 12 and the protector 13 do not have their temperature settings twisted or fall off due to distortion of the toilet seat main body 6 when sitting, and can always maintain an appropriate state. Note that the same effect can be obtained even if the temperature detection element 12 and the safety device 13 are provided on the left side of the toilet seat main body 6 in the left-right width direction. Further, in this embodiment, the safety device is assumed to be an automatic reset type thermostat, but even if it is a temperature fuse, the double safety remains the same.

As described above, the present invention consists of a toilet seat main body that has a substantially symmetrical external shape and a substantially o- or horseshoe shape, and one electric charger disposed almost entirely on the inner surface of the toilet seat main body corresponding to the butt rest part. A heater, a temperature control device for controlling the temperature of the electric heater, one temperature detection element guided to the temperature control device, and one protector electrically connected in series to the electric heater. The temperature detecting element and the safety device are distributed on both sides of the toilet seat body, with the axis of symmetry in the longitudinal direction as a border, and are located on the lateral side of the toilet seat body at an approximately midpoint in the longitudinal direction. As a result, the following effects are achieved.

(1) A simple configuration with only one temperature detection element and one safety device provides double security during normal use.

(2) Even if a towel, etc. is placed on either the left or right side of the toilet seat body, and an abnormal temperature rise occurs in that area, security can be provided using either the temperature detection element or the safety device.

(3) When the user is seated, the temperature detection element and protector are installed at approximately the midpoint in the longitudinal direction of the toilet seat body, where the heat retention effect is highest and the temperature reaches its maximum, making it possible to control the maximum temperature. , there is no temperature rise due to sitting, and comfortable heating can be obtained. Furthermore, even if the temperature detection element becomes abnormal, the safety device is activated immediately, ensuring high safety.

(4) When the user is sitting, the temperature detection element and protector are installed on the side of the central part of the toilet seat body, approximately in the middle of the longitudinal direction, where the distortion is greatest, so the temperature can be detected by the distortion of the toilet seat body caused by sitting. Proper temperature control is always possible without the temperature setting of the element or protector becoming twisted or the attachment falling off.
Extremely safe and reliable.
