Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device for electric carpets, floor heating, and the like.

[0002]

2. Description of the Related Art Conventionally, a heating device of this type, for example, an electric carpet has been constructed as shown in FIG. The configuration will be described below.

As shown in the drawing, the heating means 1 is arranged in a meandering manner in the carpet body (not shown) together with the temperature detecting means 2, and the heating means 1 is temperature-controlled by the temperature control means 3. The temperature setting means 4 is for controlling the temperature of the heating means 1 at a desired temperature. The room temperature detecting means 5 detects the temperature inside the room, and even if the ambient temperature changes even if the ambient temperature is the same, the human sensible temperature also changes. Therefore, when the ambient temperature is low, the ambient temperature is corrected to be higher and the ambient temperature is higher. At this time, the set temperature is corrected to a lower value. Therefore, the temperature setting means 4 outputs a value obtained by correcting the set temperature set by the user by the value of the room temperature detection signal from the room temperature detection means 5 to the temperature control means 3 as a temperature setting signal. The temperature control means 3 controls the heating means 1 by comparing the set temperature signal from the temperature setting means 4 and the temperature detection signal from the temperature detection means 2. The display means 6 displays whether or not the temperature control means 3 controls the heating means 1 by turning on and off a light emitting diode or the like.

[0004]

Such a conventional electric carpet is usually used mainly in winter, but is also used in early spring and autumn. Early spring and autumn are warm during the day but cold in the morning and evening, so it is necessary to use electric carpets. In this case, since it is cold in the morning, heating is started on the electric carpet, and it becomes hot at noon, so heating at the electric carpet is stopped, and at night, it becomes cold again, so heating at the electric carpet is started again. There is a problem that it is very troublesome because the operation is required again.

Therefore, even if the user does not set the temperature or stop the equipment, after a certain operation, a comfortable temperature is calculated from the room temperature state, and the heating means is temperature-controlled at the calculated temperature to raise the room temperature. There has been proposed a function of stopping energization of the heating means when the temperature reaches a level at which heating is unnecessary. If you select this function, you can automatically get comfortable temperature all day long without having to operate the spring and autumn. However, if the state of the display is the same whether the heating means is under temperature control or power is off, the illusion that the heating means is being energized all day gives the misunderstanding that power is wasted. Further, since the display does not change even when the heating means is de-energized, there is a problem that there is a fear that the equipment is operating normally.

The present invention solves the above problems and has a function of automatically adjusting the control temperature of the heating means according to the room temperature and a function of stopping the energization of the heating means. The purpose of the present invention is to provide a user-friendly warming device that does not give the heat.

[0007]

In order to achieve the above object, the present invention comprises heating means, temperature detecting means for detecting the temperature of the heating means, and temperature setting means for setting the control temperature of the heating means. , A room temperature detecting means for detecting room temperature, a first control state for controlling the temperature of the heating means by comparing the signal from the temperature setting means and the signal from the temperature detecting means, and the detected temperature of the room temperature detecting means. A second control state in which the heating of the heating means is stopped when the temperature is equal to or higher than a certain temperature, and when the temperature detected by the room temperature detecting means is lower than a certain temperature, detection by the room temperature detecting means is performed regardless of the set temperature of the temperature setting means. A temperature control means having a room temperature and a third control state for controlling the temperature of the heating means based on a signal from the temperature detection means, the first control state and the second and third control states. Switching temperature Control state selection means, comprising a display means for displaying the first, second, third control state of the temperature control means, the first, second, the third control state of the display means of each Changing the display content is the problem solving means.

[0008]

In the present invention, when the temperature control state based on the room temperature is selected by the operation of the temperature control state selecting means by the above-mentioned problem solving means, even if the equipment is still operating when the room temperature is higher than a certain temperature, It can be clarified by changing other control states and display method that the power supply to the heating means that consumes the most power is stopped, and the user misunderstands that power is wasted and the equipment is not normal. So I don't feel uneasy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in the drawing, the heating means 1 is embedded and meandered in a carpet body 9 composed of a cover cloth 7 and a felt 8. Like the heating means 1, the carpet body 9 has a polymeric thermosensitive material. The temperature detecting means 2 consisting of is embedded and arranged in a meandering manner. The temperature setting means 10 is set by the user in order to adjust the carpet body 9 to a desired temperature. The temperature control means 11 compares the signal from the temperature setting means 10 with the signal from the temperature detection means 2 to control the temperature of the heating means 1 in a first control state (hereinafter, referred to as "control state by set temperature"). A second control state in which the energization of the heating means 1 is stopped when the temperature detected by the room temperature detection means 5 is higher than a certain temperature,
When the detected temperature of the room temperature detecting means 5 is lower than a certain temperature, the heating means 1 is based on the detected room temperature of the room temperature detecting means 5 and the signal from the temperature detecting means 2 regardless of the set temperature of the temperature setting means 10.
Has a third control state (hereinafter, the second control state and the third control state are collectively referred to as "room temperature control state"). The control state according to the set temperature and the control state according to the room temperature are switched by the temperature control state selecting means 12. The display unit 13 is composed of a light emitting diode or the like, and displays the three types of control states of the temperature control unit 11. In this embodiment, one light emitting diode is used,
Three types of control status are displayed.

An example of the operation of the above configuration will be described with reference to FIG. FIG. 3 shows the relationship between the surface temperature and the display when the control state and the room temperature change. In the section a in FIG. 3, the temperature control state selection means 12 indicates that the “control state by set temperature” for controlling the temperature of the heating means 1 to the temperature set in the temperature setting means 10 is selected. Here, the display means 13 is displayed with the light emitting diode turned off. At this time, the room temperature is changing, but the heating means 1 is temperature-controlled at the set temperature set by the temperature setting means 10 regardless of the change of the room temperature.
Here, at the point d in FIG.
Is switched to "control state at room temperature". After that, the set temperature set by the temperature setting means 10 becomes invalid, and the control temperature of the heating means 1 is determined by calculation by the temperature control means 11 from the room temperature detection signal detected by the room temperature detection means 5. By selecting this function, it is not necessary to readjust the set temperature of the temperature setting means 10 every time the room temperature fluctuates, and the control temperature of the heating means 1 is automatically adjusted to the comfortable temperature. In FIG. 3, the region where the room temperature is equal to or higher than the temperature Ta is
The temperature at which it is determined that the heating unit 1 does not need to be energized is shown in the "controlled state at room temperature". Since the room temperature is higher than the temperature Ta at the point d, the temperature control means 11 stops energizing the heating means 1. At this time, the display means 13 causes the light emitting diode to light up in green. Thereby, the user can instantly know that the power supply to the heating means 1 has been stopped. Therefore, there is no misunderstanding that the electric power is wasted, and the situation that the automatic driving is canceled due to the misunderstanding does not occur. Although the heating means 1 is in a non-energized state during the section b in FIG. 3, the temperature control means 11 determines that the heating means 1 needs to be energized when the room temperature falls to the temperature Ta. Then, the control temperature of the heating means 1 is calculated by the room temperature detection signal from the room temperature detection means 5, and the temperature control of the heating means 1 is started at the control temperature obtained by the calculation. At this time, the lighting color of the light emitting diode is changed to red on the display unit 13 to indicate that the energization of the heating unit 1 is started. Thereafter, as can be seen when the room temperature drops to the temperature Tb in FIG. 3, the control temperature of the heating means 1 is changed by the change of the room temperature to perform the temperature control.

[0012]

As is apparent from the above embodiments, according to the present invention, the control state in which the energization of the heating means is stopped when the detected room temperature is higher than the constant temperature and the room temperature when the detected room temperature is lower than the constant temperature. By providing a different display depending on the control state for controlling the temperature of the heating means based on the above, it is possible to provide a user-friendly warming device that does not cause the user to worry about power consumption and can check the current control state at a glance. be able to. Further, since the three control states are displayed by one light emitting diode by using the two-color light emitting diode, the display unit does not have a complicated configuration, and the contents of the control state can be easily confirmed.
