Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating device for a toilet seat installed on a toilet bowl.

Structure of conventional example and its problems In this type of conventional toilet seat heating device, as shown in FIG. The temperature of the seat body 1 was detected by a sensor 3. In addition,
In FIG. 1, reference numeral 4 denotes a rear case, and inside the rear case 4 there is a control means for controlling the heater 2 based on the signal from the sensor 3 to keep the temperature of the seat 1 at a set temperature. 5 is stored.
6 is a power cord for supplying power to the control means 5, and 7 is a power switch. In the configuration shown in FIG. 1 above, since the control means 5 is provided,
It is possible to always maintain the seat body 1 of the toilet seat at an optimum temperature, for example, 41°C.

However, in recent years, there has been an increase in the use of toilet seat covers to eliminate the cold feeling the moment you sit on the seat 1, as well as to maintain a sense of hygiene or to freely change the color. There has been a problem in that when the toilet seat cover is attached, the temperature felt by the human body becomes lower, and as a result, a satisfactory sense of warmth cannot be obtained. In addition, when using a commercially available cloth toilet seat cover, the optimal sense of warmth can only be obtained by setting the temperature approximately 3 degrees Celsius higher than normal. Therefore, when using a toilet seat cover, you always get an unsatisfactory feeling of warmth, and even when the temperature setting is variable, the setting is unclear, so you can only get an unsatisfactory feeling of warmth. The problem was that it was difficult to use because it was difficult to use, or the appropriate temperature display range was off.

OBJECTS OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to make it possible to easily select an appropriate temperature whether a toilet seat cover is not attached or when it is attached.

Structure of the Invention In order to achieve the above object, the present invention is provided with a switching means for switching the set temperature depending on whether or not the toilet seat cover is attached. By setting the switching means depending on the presence or absence of the temperature, it is possible to easily obtain the appropriate temperature.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In addition, this figure 2 and 3
In the figure, the same parts as those in FIG. 1 showing the conventional example are given the same numbers. In FIG. 2, 8 is a power supply, 9 is a rectifier bridge that rectifies the power supply 8, 10 is a changeover switch, 11 and 12 are resistors that regulate the amount of charge to the capacitor 13, and 1
4 and 15 are resistors for obtaining a potential, 16 is a trigger element, 17 is a pulse transformer, and 18 is a power control element.

Further, FIG. 3 shows the configuration of the operating section in the above embodiment, where 7 is a power switch, 10 is a changeover switch, and 19 is a name plate.

In the above configuration, when the cover is not attached, the changeover switch 10 is switched to the one without the cover as shown in FIG. 3, and the power switch 7 is turned on. As a result, the resistors 11,1
The charging amount determined by the series resistance value of 2 and the resistance 1
The electric power of the heater 2 is controlled according to the potential determined by the resistance values of the heaters 4 and 15 and the sensor 3, and the temperature is automatically controlled to a constant temperature of 41° C., for example. on the other hand,
When the toilet seat cover is attached, the changeover switch 10 is switched to the one with the cover. As a result, the resistor 11 shown in FIG. 2 is shorted and the charging speed of the capacitor 13 is increased, so the phase of the trigger is advanced, and as a result, for example, the seat body becomes 3 degrees Celsius higher than before and reaches 44 degrees Celsius. Since the temperature is automatically controlled, the surface of the toilet seat cover provides an optimal sense of warmth.

In this way, in one embodiment of the present invention, anyone can easily recognize the necessity of switching, and can switch the set temperature depending on whether or not there is a toilet seat cover, so it can be adjusted at any time depending on the situation. It has the feature of being able to provide an optimal sense of warmth.

FIG. 4 shows the configuration of the operating section in another embodiment of the present invention, in which a variable resistor 20 that can vary the set temperature is provided. In terms of circuitry, it is provided in series with the resistor 14 in FIG. 2, for example. Although the optimum temperature range is shown in Fig. 4, this optimum temperature range also deviates depending on the presence or absence of the toilet seat cover, and if there is no changeover switch 10, it will mislead the user and result in unsatisfactory heating. However, since the changeover switch 10 is provided as shown in Fig. 4, the changeover switch 10 can be operated according to the situation. For example, the appropriate temperature range display of the variable resistor 20 for temperature setting can be used as is;
The user can definitely get the right temperature.

Effects of the Invention As described above, the toilet seat heating device of the present invention is provided with a switching means for switching the set temperature depending on whether or not the toilet seat cover is attached. It has the excellent feature of not only being recognizable, but also being able to easily obtain the optimal sense of warmth at any time by switching the changeover switch.
