度に対する誤差を少なくするような工夫がされている。[Prior Art] Floor heating has recently attracted attention as a heating means in winter, but electric carpets are the most widely used at present. In a conventional electric carpet, a control is performed by using a surface temperature sensor or a room temperature sensor so as to keep the surface temperature of the carpet as constant as possible, so that an error with respect to a target temperature is reduced.

てきてしまうという欠点がある。[Problems to be Solved by the Invention] FIG. 3 shows the change over time of the surface temperature of the conventional electric carpet, where the broken line indicates a case where the output of the electric carpet is set to be strong, and the solid line indicates a case where the output is set to be weak. It is. As is clear from this figure, in the conventional electric carpet,
Since the surface temperature is controlled so as to be kept constant, there is a drawback that, when used for a long time, heat is trapped in the contact portion between the user and the carpet.

暖かさが物足りないという欠点があった。The dashed line in FIG. 4 indicates the time change of the skin temperature when the setting is relatively strong, the solid line indicates the time change of the skin temperature when the setting is weak, and the broken line indicates the time change of the subjective evaluation of the warmth when the setting is relatively strong. Is the time change of the subjective evaluation of warmth when set weakly. Here, the subjective ratings are "hot", "pretty warm", "somewhat warm", "insensitive",
The display is divided into five stages of “cool”. If the user sets it higher to sit and feel the warmth immediately,
Over time, as indicated by the dashed line, it gradually feels hotter. On the other hand, if the setting is weak, there is a drawback that the warmth is insufficient for several tens of minutes after sitting, as shown by the solid line.
本発明はこのような点に鑑みてなされたものであり、
その目的とするところは、使用開始初期から充分に暖か

る。The present invention has been made in view of such a point,
An object of the present invention is to provide an electric carpet that can sufficiently feel warmth from the beginning of use and that does not become hot even after long use.
［課題を解決するための手段］ 本発明の電気カーペットにあっては、上記の課題を解
決するために、第１図に示すように、カーペットの表面
温度を使用者が涼しく感じない程度の温度に保つような
低い通電率とする低通電率期TLと、充分に暖かさを感じ

率期THとが交互に起こり、低通電率期TLの持続時間が1/
fゆらぎで変化するように制御されることを特徴とする
ものである。[Means for Solving the Problems] In the electric carpet of the present invention, in order to solve the above-mentioned problems, as shown in FIG. 1, the surface temperature of the carpet is such that the user does not feel cool. the low duty ratio as keep a low duty factor period T L, sufficiently occur high duty factor-life T H and alternately to temporarily increase the duty ratio so as rise in temperature to feel the warmth, low power The duration of the rate period T L is 1 /
It is characterized by being controlled to change with f fluctuations.
ここで、高通電率期THの持続時間は１分乃至３分程度
であり、低通電率期TLの持続時間は１分乃至10分程度の
間で1/fゆらぎで変化することが好ましい。Here, the duration of the high duty ratio period T H is about 1 minute to 3 minutes, the duration of the low duty ratio period T L is to be changed in 1 / f fluctuation between about 1 minute to 10 minutes preferable.
［作 用］ 本発明の電気カーペットにあっては、高通電率期THに

わらないか、むしろ少なくなる。In the electric carpet in the work for the present invention, since the high duty ratio period T H relatively fast temperature rises, the user can feel securely warmth. In addition, since the high duty ratio period T H temperature also been switched to low power rate period T L from is gradually lowered, warm feeling of the user is not be immediately eliminated. Since reliably warm feeling in a high duty factor period T H occurs, the surface temperature in the low duty ratio period T L may be set lower than conventional electric carpet, therefore, without the temperature continues to rise It doesn't get hot even after long use. Also, the amount of power per hour is almost the same as or less than that of the conventional one.

The duration of the low duty cycle TL is 1 / f between 1 minute and 10 minutes
By controlling so as to change with fluctuation, the most desirable usability is obtained.

気カーペットと同程度以下である。FIG. 1 and FIG. 2 show an embodiment of the present invention. Waveform B of Figure 1 shows the duty factor, high duty ratio period T H is about 1 minute, the low duty ratio period T L is varied by 1 / f fluctuation between about 1 to 5 minutes. As a result, the surface temperature of the electric carpet changes as shown by a curve A in FIG. By providing a high duty factor-life T H intermittently, so that the surface temperature is higher than the occasional base temperature t 0. At this time, the skin temperature of the user changes as shown by a curve C in FIG.
Accordingly, the subjective evaluation of warmth changes as shown by a curve D in FIG. That is, since synchronism with a high duty factor-life T H results in a feeling of warmth, it is possible to feel the warmth from the use start early. In addition, since the surface temperature gradually decreases, the feeling of warmth does not disappear immediately, and the user does not feel cool even in the low duty ratio period TL . Then, the time interval of occurrence of high duty factor-life T H changes according to the duration of the low duty ratio period T L, is the duration
Since the fluctuation is 1 / f, the user does not feel monotonous or accustomed. Furthermore, since the positively warm feeling in a high duty factor period T H occurs, the surface temperature in the low duty ratio period T L is
Since it may be set lower than the conventional electric carpet, it does not feel hot even when used for a long time, and the electric power used is less than or equal to that of the conventional electric carpet.

う利点がある。[Effects of the Invention] In the electric carpet of the present invention, as described above, the high duty cycle and the low duty cycle are alternately performed, and the duration of the low duty cycle is controlled to change with 1 / f fluctuation. Therefore, the user feels warmth in synchronization with the high duty cycle, and does not feel cool even in the low duty cycle. The time interval in which the high duty cycle occurs is the duration of the low duty cycle, that is, 1 / f fluctuation, so that the user does not feel monotonous or familiar. In addition, since a warm feeling is definitely generated during the high duty cycle, the surface temperature during the low duty cycle may be set lower than that of the conventional electric carpet. There is an effect that the electric power can be less than or equal to that of the conventional electric carpet. Further, in the present invention, since the duration of the low duty cycle period of the electric carpet is changed by 1 / f fluctuation, for example, the detection value of the heat generation power of the electric carpet and the surface temperature of the electric carpet is measured using an amplifier. There is an advantage that the configuration of the control device is simplified as compared with a method of performing continuous control so as to have 1 / f fluctuation.
