Supply.
- the resistance value of the heat source 4011 is very small, about 1Z10 or less at the time of rated power consumption when the heat source 4011 is cold (a temperature corresponding to the temperature in the toilet room), so a large rush in the beginning of energization. Current flows.
- the temperature of the heat source 4011 itself increases as the heat source 4011 generates heat, so that the resistance value of the heat source 4011 gradually increases, and the inrush current is suppressed as the resistance value of the heat source 4011 changes.
- the control means 4013 when the human body detection means 4012 detects a human body, the energization rate of the heat source 4011 that warms the toilet seat 4010 is continuously increased, so that the temperature of the toilet seat 4010 can be reduced in the minimum necessary time.
- the seatable temperature can be reached and a convenient toilet seat device can be provided.
- the heat source 4011 is not unnecessarily energized, the toilet seat device is highly energy-saving.
- FIG. 36 shows a block diagram of the toilet seat device according to the tenth embodiment of the present invention
- FIG. 37 is a graph showing changes in the toilet seat temperature.
- FIG. 36 it has room temperature detecting means 4014 for detecting the room temperature, and the control means 4013 determines a predetermined time for energizing the heat source 4011 according to the room temperature detected by the room temperature detecting means 4015.
- the temperature of the toilet seat 4010 immediately before the human body is detected and the heat source 4011 is energized differs.
- the time required for the toilet seat 4010 to reach the seatable temperature is also different. For example, when the room temperature is low, the temperature at which the toilet seat 4010 is lowered and the temperature at which the toilet seat 4010 rises is slow, so that it is necessary to energize the heat source 4011 for a long time when trying to reach the seatable temperature.
- the heat source 4011 is energized in the same time even when the room temperature is high, the temperature of the toilet seat 4010 exceeds the seatable temperature.
- the temperature of the toilet seat 4010 is high and the temperature of the toilet seat 4010 rises quickly, so it is only necessary to energize the time heat source 4011 for a short time to reach the seatable temperature of the toilet seat 4010! However, the temperature of the toilet seat 4010 does not reach the seatable temperature when the heat source 4011 is energized for the same time at the same time.
- a predetermined time for energizing the heat source 4011 according to the room temperature is set.
- the temperature of the toilet seat 4010 can reach the seatable temperature in the minimum necessary time, and an easy-to-use toilet seat device can be provided. Further, since the heat source 4011 is not unnecessarily energized, the toilet seat device is highly energy-saving.
- FIG. 38 shows a block diagram of the toilet seat apparatus according to the eleventh embodiment of the present invention.
- the toilet seat temperature detecting means 4015 for detecting the temperature of the toilet seat 4010 is provided, and the control means 4013 is a predetermined power supply to the heat source 4011 according to the temperature of the toilet seat detected by the toilet seat temperature detecting means 4015. Determine the time.
- the toilet seat 4010 is heated by the heat source 4011, if the user stops supplying power to the heat source 4011 after use, it takes some time for the temperature of the toilet seat 4010 to drop.
- the interval at which the toilet seat device is used in actual use varies depending on the installation environment, use environment, and time zone. For example, in the morning time of a family of four, toilet seat devices are used continuously during the same time for commuting and attending school. In addition, toilet seat devices are used continuously even when toilet seat devices are installed in public facilities where people frequently come and go. In these cases, since the interval at which the toilet seat device is used is very short, energization of the heat source 4011 is started while the temperature of the toilet seat 4010 is sufficiently high. Even in this case, if the predetermined time for energizing the heat source 4011 is the same time, the energization is performed more than necessary, and power is consumed unnecessarily.
- the predetermined time during which the heat source 4011 is energized is determined according to the temperature of the toilet seat 4010, so that the temperature of the toilet seat 4010 reaches the seatable temperature in the minimum necessary time. Therefore, an easy-to-use toilet seat device can be provided. Further, since the heat source 4011 is not energized unnecessarily, the toilet seat device is highly energy-saving.
- toilet seat temperature detection means 4015 is installed inside the toilet seat.
- the present invention is not limited to this, and it is the same if the position is highly correlated with the surface temperature of the toilet seat such as the surface of the toilet seat. An effect can be obtained.
- the present invention is useful as a heating device in contact with a human body.
- the present invention can be applied to other uses such as heating appliances because it is possible to control a heat source with high energy saving performance.
