Abstract

PURPOSE:To save energy consumption in an electric 'Kotatsu' (foot warmer), by providing a temperature sensor, which controls to lower the temperature in the 'Kotatsu' in some degree when the air flowing through an air passage has kept a constant temperature for a long time, in the air passage in a heater unit. CONSTITUTION:A fan unit 2 and heaters 1 and provided to a heater unit 7. The heater unit 7 is fitted to the back side of the top plate of a 'Kotatsu' framework 8. A temperature sensor 5 is installed in an air passage 6 in the heater unit 7. It controls the temperature in the 'Kotatsu', and controls to lower the temperature in it in some degree when the air flowing through the air passage 6 in the heater unit 7 has kept a constant temperature for a long time. Although the function to keep a set temperature in the 'Kotatsu' and the heating capacity during taking warmth out of it are the same as those of conventional appliances, the point of this device is energ-saving. The temperature sensor 5 controls to lower the temperature when nobody is taking warmth at the 'Kotatsu' and a set temperature has been kept constant for a predetermined time.

BACKGROUND OF THE INVENTION The temperature inside a conventional electric kotatsu is controlled as follows. First, a heating element unit consisting of a heater, air blower, etc. is generally installed in the center of the back of the tower, but a temperature sensor is installed inside this heating element unit, and the temperature inside the kotatsu is measured based on this temperature. It was monitored by sensors and controlled the amount of electricity supplied to the heater to maintain the desired temperature. There are two types of temperature sensor and energization control devices: one that uses a thermostat to directly control the energization of the heater, and one that measures the temperature with a semiconductor sensor and controls the amount of energization to the heater using an electronic circuit. Ta. There are other methods for controlling the air volume (/i), but there is a certain temperature scale (F- setting).

Looking at the temperature change inside the kotatsu after turning it on,
All the methods had temperature characteristics as shown by the dotted line in Figure 2.

In other words, when you turn on the switch, the heater and air blower operate to raise the temperature inside the kotatsu, and when it eventually reaches the desired set temperature, the temperature sensor controls the amount of electricity supplied to the heater, and the temperature inside the kotatsu is adjusted from then on. It worked to keep it constant.

Problems to be Solved by the Invention In the conventional technology as described above, the temperature of the electric kotatsu has a function to maintain the temperature once it has warmed up to the desired set temperature after turning on the switch. there were.

As a result, the temperature inside the kotatsu remained at the set temperature forever, regardless of whether or not someone was warming the kotatsu.

Therefore, it would be good if there was always someone there to take the temperature.1 In daily life, there are many chances that the temperature will continue to be maintained at the set scale even without someone taking the temperature. Especially when the temperature is set to a high temperature, it will be warm and comfortable when someone is there to take the heat, but maintaining a high temperature when there is no one to take the heat means high electricity bills and energy loss. In addition, high temperatures had negative effects such as reducing safety and shortening the lifespan of each component.

Means to Solve the Problems In order to solve the problems seen in the conventional example, the kotatsu, which has a heating element unit at the bottom using an air blower, is heated when there is no person warming the kotatsu or when the person is lying down inside the kotatsu and does not move the kotatsu at all. In cases such as when the kotatsu runs out, the temperature of the air flowing through this air path remains constant, and in cases such as when the person taking the heat goes in and out of the kotatsu or moves inside.

Pay attention to the fact that the temperature of the air flowing through this air path changes, and depending on whether it is a constant temperature or an unstable temperature that is changing, you can either maintain the set temperature inside the kotatsu or change it. For example, this problem can be solved by installing a temperature sensor in the air passage inside the heat generating unit, which causes another control circuit to control the temperature, such as lowering the temperature if no one is there to take the heat.

作用 上記構成によって、採暖者の有無をキャッチし。action With the above configuration, it is possible to detect whether there is a person taking heat.

The kotatsu temperature is further controlled, and its function is as follows.

When you turn on the power, the heater is energized, warming the inside of the kotatsu, and the temperature sensor monitors the temperature.

When the set temperature is reached, the power to the heater is controlled to maintain the set temperature constant.

Here, the air inside the kotatsu is sucked into the heating element unit by the blower, and is then blown out using the inside as an air path, so that the air inside the kotatsu is stirred and the temperature inside the kotatsu is evened out.

At this time, by installing a temperature sensor in the air path, the temperature inside the kotatsu can be detected accurately and more sensitively.

In other words, depending on whether the temperature of the temperature sensor installed in the air path is constant, or unstable, such as rising, falling, or changing up and down, The temperature inside the kotatsu is maintained at the set temperature as determined by the control circuit.

As a result, when there is no one taking the heat, the temperature of the kotatsu remains constant, so it is controlled to lower it below the set temperature, and since it is lukewarm than the set temperature and is changing during heating, it is controlled to raise it by changing the set temperature. Furthermore, when a warmer enters and exits the kotatsu, or moves around inside the kotatsu to warm himself up, the temperature sensor installed in the air passage detects that the temperature of the air flowing through the air passage is unstable. The temperature is controlled to maintain the set temperature.

Furthermore, whether the temperature state of the temperature sensor 5 is maintained at a constant temperature or is in an unstable state that is changing is determined by the control process in the external controller 9. If the temperature is constant, the temperature is controlled to be lower than the initially set temperature. Here, the installation position of the temperature sensor 5 is set in the suction air path near the suction port 61, as this is the place where the temperature inside the kotatsu can be most sensitively detected among the 1 heating element units 7. I can know the temperature.
