取り去つた時に熱過ぎるということになる。(Background Art) Electric heating carpets such as electric carpets have a film-like or cord-like heater with a slight surface finish such as felt, and can be used alone, but depending on the preference of the user. It is often used with various covers. In this case, the problem is that the surface temperature of the cover varies depending on the thickness of the cover used. In other words, the temperature near the heater is controlled by the operation of the temperature control circuit to match the set temperature given by the temperature regulator, but differences in the cover surface temperature occur due to differences in the thermal conductivity of the cover. It is something. Therefore, if the set temperature remains unchanged without the cover, the temperature will drop when the cover is used, making it feel lukewarm, and conversely, if the temperature is appropriate when using the cover, it will become too hot when the cover is removed.

In addition, the upper limit temperature of the electric heating rug is set for the case where the cover is not used for safety reasons, so when the cover is used, there is always something lacking in terms of temperature.

さを推定することが可能である。 By the way, covers for electric heated rugs range from simple cloth-like covers used to simply prevent dirt to thick, long-pile Saxony-type covers designed for interior design. The applied cover differs from ordinary carpet in that the fabric weight, pitch, etc. of the fibers are designed to improve heat conduction, and have the property of transmitting light to a certain extent. The amount of light transmitted has a certain degree of correlation with the thickness of the cover, and therefore it is possible to estimate the thickness of the cover based on the amount of light transmitted.
第４図はカバー厚と透過光量の相関関係を示し

しない。 Figure 4 shows the correlation between the cover thickness and the amount of transmitted light. In the figure, the horizontal axis shows the cover thickness used, and the vertical axis shows the amount of transmitted light. For example, a is the state without a cover, and b is the state where there is no cover. A thin simple cover, c corresponds to a medium-thick cover such as velor, and d corresponds to a thick cover such as Saxony.In particular, d corresponds to a thick cover such as Saxony, which hardly transmits light. .

I am trying to make corrections to the control settings.

入力端子に与える。 Hereinafter, referring back to FIG. 3, the operation of the circuit will be explained. When the commercial power supply 1 is turned on, DC power is applied to each part from the rectifying and smoothing circuit 6, and the circuit enters an operating state.
At this time, the voltage dividing circuit 4 is connected to the sensor electrode S 1 of the heating element 2.
An alternating current voltage is applied through the temperature detector 5, and a voltage corresponding to the voltage division ratio between the impedance of the voltage dividing circuit 4 and the impedance of the heat-sensitive material interposed between the sensor electrodes S1 and S2 is input to the temperature detector 5. The temperature detector 5 performs processing such as rectification, smoothing, and noise removal, and provides a detection signal having a characteristic of decreasing as the temperature increases to a non-inverting input terminal of a comparator CP constituting a comparison circuit.

べく制御されることになる。 However, at the initial stage of startup, the heating element 2 is not yet sufficiently warmed up, so the comparator CP
The voltage applied to the non-inverting input terminal of is sufficiently high,
Therefore, the output of the comparator CP becomes positively saturated, which turns on the transistor Tr and turns on the relay Ry.
, and turns on the contacts Rya 1 and Rya 2 to energize the heater H. Thereafter, when the temperature of the heating element 2 rises due to energization of the heater H, the impedance of the heat-sensitive material interposed between the sensor electrodes S 1 and S 2 decreases, and the impedance is applied to the non-inverting input terminal of the comparator CP. The temperature detection signal decreases and finally falls below the set value applied to the inverting input terminal of the comparator CP, causing the output of the comparator CP to be inverted. As a result, the transistor Tr turns off and the drive of the relay Ry is also stopped, so the contact
Rya 1 and Rya 2 are also turned off, power supply to the heater H is stopped, and heating of the heating element 2 is stopped. Also,
The comparator CP has hysteresis in a certain width due to the positive feedback resistor R4 , and when the temperature detection signal rises as the heating element 2 cools and exceeds the hysteresis width, it is inverted again and the transistor Tr
The heater H is energized by the operation of the relay Ry.
Thereafter, these operations are repeated, so that the heating element 2 is controlled to match the set temperature corresponding to the set value applied to the inverting input terminal of the comparator CP.

す煩わしさが大幅に軽減されることになる。 On the other hand, the variable resistor VR as a temperature regulator is manually operated according to an indication scale (not shown), and the resistance value R VR of the variable resistor VR and the resistances R 1 , R 2 , The voltage set by R 3 is applied to the inverting input terminal of the comparator CP, but the phototransistor connected across the resistor R 1
Correction is applied according to the amount of light transmitted through the cover by changing the resistance of the PHTr. For example, in the state without a cover corresponding to a in Fig. 4, the phototransistor PHTr is directly exposed to the light beam, so it is completely conductive, and the set voltage (voltage applied to the inverting input terminal of the comparator CP) V at that time is: If the DC voltage given from the rectifier and smoothing circuit 6 is V D , then V(a)=R 3 +R VR /R 2 +R 3 +R VR・V D , and a thick cover such as Saxony corresponding to d in Figure 4. Since the light is completely blocked, the phototransistor PHTr is turned off, and the set voltage V becomes V(d)=R 3 +R VR /R 1 +R 2 +R 3 +R VR ·V D. Further, in the middle, V(a)>V>V(d), and as the thickness of the cover becomes thicker, the set value decreases, and the set temperature of the heating element 2 is increased. Therefore, the decrease in surface temperature due to the presence of the cover is compensated for, and the trouble of redoing settings depending on the type of cover is greatly reduced.
