Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heated toilet seat that heats the seat body of the toilet seat to an appropriate temperature.

Conventional construction and problems thereof A conventional heated toilet seat was constructed as shown in FIGS. 1 and 2. That is, FIG. 1 is a top view of a conventional heated toilet seat, and FIGS. 1 and 2 are cross-sectional views of a sensor installation part in the conventional example.

1 is a seat body of the toilet seat; 2 is a heater installed on the back surface of the seat body 1 for heating the seat body 1; and 3 is a heater installed on the back surface of the seat body 1; , and a sensor for detecting the temperature of the seat body 1; 4 is a control device that keeps the temperature of the seat body 1 constant by controlling the heater 2 according to the temperature signal from the sensor 3; A power cord for supplying power to the control device 4; 6 a temperature setting device for setting the control temperature of the seat 1; 7 housing the control device 4, the temperature setting device 6, etc.; 8 is a human body sitting on the seat body 1; 9 is a back plate of the seat body 1; 10 is a case from the heater 2 to the sensor 1;
0, and 11 indicates the flow of heat from the heater 2 to the seat body 1 and the human body 8.

In the above-described conventional configuration, when the human body 8 is not present, most of the heat from the heater 2 is applied to the seat 1, and in this case, the heater 2 and the seat 1
The temperature of the seat body 1 is almost the same, so the sensor 3 can accurately detect the temperature of the seat body 1,
Stable control can be performed. However, when there are three human bodies 8, the heat of the heater 2 is taken away by the human body 8 as shown in the heat flow at 11, so the human body 8 feels warm due to the heat. The conventional configuration described above had the following drawbacks.

That is, the surface temperature of the human body 8 at the part where the human body 8 contacts the seat body 1 is about 33°C, and the control temperature of the seat body 10, which the human body 8 feels is comfortably warm, is about 40°C.
C, and therefore, the amount of heat corresponding to the difference between the 40'C and 33°C is stably given to the human body 8,
However, in the conventional configuration described above, the sensor 3 is installed approximately in the center of the seat body 1, so that the sensor 3 is located directly above the seat body 1 where the sensor 3 is installed. As a result, the temperature of the seat body 1 decreases. Therefore, the sensor 3 detects the drop in temperature and attempts to increase the amount of electricity supplied to the heater 2 in order to return the temperature to the original temperature, but this is hardly observed.
Therefore, the increase in the amount of current supplied to the heater 2 becomes considerably large. Therefore, while the human body 8 continues to sit on the seat body 1, the human body 8 often feels very hot and uncomfortable, and in extreme cases, it may even cause low-temperature burns.

Purpose of the Invention In view of the above-mentioned conventional problems, the present invention provides a sensor that is installed away from the position affected by the human body, which is a constant heat source. The purpose of this invention is to provide a heated toilet seat that is free from the danger of

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a structure in which, when a human body sits on the seat body of a toilet seat, the seat is placed at approximately the rear end or approximately at the tip of the seat body, where there is almost no contact between the human body and the seat body. It is equipped with a sensor that detects body temperature.

With the above configuration, even if the human body comes into contact with the sitting body, there is no abnormal increase in the amount of electricity applied, and as a result, a stable constant amount of heat is supplied to the human body, so the human body feels comfortable and warm. This is something that can be obtained.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. FIG. 3 shows a top view of the heated toilet seat according to an embodiment of the present invention, and FIG. 4 is a side view of the heated toilet seat. Note that in FIGS. 3 and 4, the same numbers as those in FIGS. 1 and 2 shown in the conventional example indicate the same parts, and therefore, the explanation of those parts will be omitted. 12
13 indicates the toilet bowl, 13 indicates the toilet seat lid, and A, B, and C indicate the positions of the seat body 1.

In the above configuration, the sensor 3 is installed substantially at the rear end of the seat body 1, and therefore, the sensor 3 is located at the human body 8.
is removed from the position where it contacts the seat body 1, and as a result, it is not affected by the human body 8 as a constant heat source,
Since the heater 2 can be controlled with the amount of energization that makes the temperature near the sensor 3 constant, an abnormal increase in the amount of energization caused by the human body 8 sitting on the seat 1 is eliminated.

Page 6; F The installation position of the sensor 3 shown in FIG. 3 is approximately at the rear end of the seat body 1, and as is clear from FIG. Since the rear case 7 and the toilet seat lid 13 are present at the rear of the human body 8, there is a gap even in an obese human body, and there is almost no contact between the sensor 3 and the human body 8. Therefore, the sensor 3 is not limited to the position shown in FIG. 3, but the same effect can be obtained even when the sensor 3 is placed at the substantially rear end portion of the seat body 1 indicated by B. Furthermore, considering the usage situation of the toilet seat where most users sit with their legs slightly open, there is almost no contact between the sensor 3 and the human body 8 even at the approximate tip of the seat body 1 as shown in position C. However, the same effect as in the above embodiment can be obtained.

Effects of the Invention As is clear from the above description, the heated toilet seat of the present invention includes a seat body of the toilet seat and a heater that heats the seat body, and the seat is provided at approximately the rear end or approximately the front end of the seat body. A sensor that detects the body temperature is installed, and a control device that controls the heater according to the temperature signal from this sensor is installed, so even when a person is sitting on the seat, the sensor is installed directly above the sensor installation position. The foot heat source, the human body, no longer comes into contact with the foot heat source, and as a result, even if the heat of the heater is absorbed by the foot heat source side and the amount of electricity applied to the heater increases, the temperature detected by the sensor falls! , ``1. Abnormal control conditions that do not return to normal will no longer occur, and as a result, a stable control condition can be maintained, so a constant amount of heat will always be given to the human body. It has the excellent feature of not only providing a comfortable sense of warmth, but also preventing the risk of low-temperature burns.
