Abstract

PURPOSE:To make it possible to use an electric carpet for the purpose other than a heater effectively by obtaining a temperature higher than the ordinary use only when the carpet main body to which a condition sensor is furnished is made in a turnover position. CONSTITUTION:When an electric carpet is used as an ordinary heater, a condition sensor 20 is set to turn to the OFF condition, the second temperature setting member 19 is also OFF consequently, and the temperature of the electric carpet is kept at the value set by the first temperature setting member 16. On the other hand, when the electric carpet is used for the tick killing purpose other than the heating purpose, a temperature controller 22 installing the condition sensor 20 is turned over by doubling the surface of the carpet to the inner side, for example, to turn the condition sensor 20 ON, and the second temperature setting member 19 is also turned ON. As a result, the carpet can be set at a temperature higher than the ordinary temperature setting. The highest temperature can be converted automatically responding to the case of using the carpet for an ordinary heater, and using for the other purpose, accordingly.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to electric carpeller temperature control.

BACKGROUND OF THE INVENTION The electric circuit of a conventional electric carpet has a configuration as shown in FIG. That is, signals from the temperature sensor 1 are processed by the detection circuit section 2, and based on these output signals, electricity is controlled to be supplied to the heater 4 via a power controller 3 such as a relay, thereby controlling the temperature of the carpet. It was something. Here, the temperature setting resistor 6 and the temperature setting variable resistor 6, which are resistors connected in series with the temperature sensor 1, are resistors for setting the carpet temperature. That is,
The maximum temperature was defined by the temperature setting resistor 6, and the temperature setting variable resistor 6 allowed the user to arbitrarily set the temperature to be lower than the above-mentioned maximum temperature.

Problems to be Solved by the Invention However, in an electric carpet with such a circuit configuration, the maximum temperature is uniquely determined, so even if you try to set it to a higher temperature for purposes other than using it as a regular heating device, it will not work. There wasn't.

7 "Kiki - When using pets for purposes other than heating, if you fold the surface in half and energize it, the heat will kill the guni, so you can use this kind of mite killer. When the purpose of use was to achieve effectiveness, it was necessary to set the temperature as high as possible.On the other hand, when used as a normal heating device, it was necessary to prevent low-temperature burns,
Considering safety under local heat retention, the maximum temperature could not be set to a moderately high temperature.

Therefore, in the conventional method, the maximum temperature that can be set manually is set in consideration of misuse, and in order to maintain safety, it is not possible to reach a high temperature, and it is not possible to set the maximum temperature manually. When in use, there was a problem in that sufficient effects could not be obtained because the temperature could not be set higher than that.

The present invention solves the above problems and provides an electric carpet whose maximum temperature automatically changes depending on whether it is used as a normal heater or for other purposes.

Means for Solving the Problems In order to solve the above-mentioned problems, the electric carpet of the present invention includes a main body in which a heat generating part is disposed, and a first temperature setting part for setting the temperature of the main body. A second temperature sensor, wherein the main body is provided with a state sensor for detecting a reversed state of the main body, and the temperature of the main body is set to a higher temperature than the maximum temperature set by the first temperature setting section based on the output of the state sensor. It is equipped with a temperature setting section.

Operation In the above configuration, when the main body portion in which the condition sensor is disposed is spatially reversed, the output of the condition sensor causes the second temperature setting section to lower the maximum temperature set by the first temperature setting section. You will also need to set the main body temperature to a high temperature.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is an electric circuit of the electric carpet of this embodiment, and FIG. 2 is a perspective view of the electric carpet.

In the figure, 11Fi power is a temperature sensor that detects the temperature of the PET body 12, and the signal of this temperature sensor 11 is processed by the detection circuit section 13, and these output signals are transmitted via a power controller 14 such as a relay, Carpet body 12
The temperature of the carpet is controlled by controlling the electricity supply to the heater 15 disposed in the carpet. Here, 16 is a first temperature setting section connected in series with the temperature sensor 11, and a temperature setting resistor 17 for setting the maximum temperature, and the temperature of the carpet body 12 can be arbitrarily set to a temperature lower than the above-mentioned maximum temperature. It consists of a temperature setting variable resistor 18.

Further, 19 is a second temperature setting section connected in parallel with the first temperature setting section 16, and this second temperature setting section 19 has a state sensor 20 and a temperature setting resistor 21 disposed on the carpet body 12. It consists of Note that 22 is a temperature controller provided in one corner of the carpet body 12, and houses a detection circuit section 13, a power controller 14, a first temperature setting section 16, a second temperature setting section 19, and the like.

Next, an example of the state sensor 20 of the second temperature setting section 19 will be described in detail. In Fig. 3, the cylindrical case 2
A conductive substance, such as mercury 20b, is sealed in Oa. An electrode 20c is provided on the upper surface of the cylindrical case 20d.
, 20d are provided. Such a state sensor 2
0 is a normal state, that is, the mercury 20b is the electrode 20c, 20
When the electrode 20c and the electrode 20d are not in contact with each other, the electrode 20c and the electrode 20d are in an insulated state. However, when the state sensor 20 is spatially reversed, the mercury 20b comes into contact with the electrodes 20C and 20d, so that the electrodes 20c and 20d are in a dedicated state.

With the above configuration, the operation of the electric carpet of this embodiment will be explained. In other words, the electric car vent is shown in Figure 1 (
When used as a suitable heater as shown in a),
The state sensor 20 is arranged to be in the 0FFO state, so the second temperature setting section 19 is also turned off, and the temperature of the electric carpet becomes the temperature set by the first temperature setting section 16.

However, when using a 7E air carpet for purposes other than heating, such as killing mites, for example, when the surface is folded inward as shown in Figure 2(b), the shape Since the temperature controller 22 is reversed, the status sensor 20 is turned on, and the second temperature setting section 1 is turned on.
9 is turned on. Therefore, the temperature of the carpet is determined by the combined resistance of the temperature setting resistor 17 of the first temperature setting section 16, the variable temperature setting resistor 1B, and the temperature setting resistor 21 of the second temperature setting section 19. Furthermore, since this combined resistance can always be made smaller than the series resistance of the temperature setting resistor 17 and the temperature setting variable resistor 18, it is possible to set the temperature higher than the normal temperature setting. Also, if the resistance value of the temperature setting resistor 21 is set to a relatively small value compared to the resistance value of the temperature setting variable resistor 1 day, the user can easily set the resistance value of the temperature setting variable resistor 18 to a large value during normal use. However, since the value of the temperature setting variable resistor 18 is almost ignored, the above-mentioned combined resistance value is automatically set to a high temperature regardless of the temperature adjustment scale.

FIG. 4 is a graph showing the rise in carpet surface temperature when the carpet is set to a higher temperature than the maximum temperature obtained in normal use. During normal use, the carpet surface temperature should be between 45℃ and 50”0 when considering safety.
It is appropriate to set the temperature to 1M degrees, but in order to exterminate mites, generally a temperature of 50'C or higher is sufficient to kill them in a short time. Therefore, when used for the purpose of miticidal effect, 50"C~
It is effective to raise the carpet surface temperature to 56"GK.Moreover, even at this high temperature, as mentioned above,
Because it is used by folding it in two, the user does not step on the carpet surface and there is no risk of low-temperature burns, and there is also no risk of abnormally high temperatures caused by local heat retention when cushions, etc. are placed. Since there is no heat, it is possible to raise the temperature to high temperatures while ensuring safety.

As another embodiment of the present invention, as shown in FIG. S, there is a configuration in which a timer circuit 23 is added as a component of the second temperature setting section. This is input to the timer circuit 23 when the above-mentioned state sensor 20 is in the ON state,
From this state, the timer counts, and a signal is sent to the detection circuit section 13 so that the heater is energized for a certain period of time. Therefore, when the electric current is applied twice to exterminate ticks, the temperature is set higher than normal, but after the electric current has been applied for a certain period of time, it can be automatically stopped. Therefore, not only energy saving effect but also safety is further improved.

In addition, in this example, the temperature setting resistor is temperature sensor 1.
1 has been described, but it may also be included in the detection circuit section 13, and the same results as described above can be obtained in this case as well.

Effects of the Invention As is clear from the description of the embodiments above, the electric carpet of the present invention can obtain a higher temperature than usual only when the main body portion in which the condition sensor is disposed is placed in the reverse position.
It is also effective for uses other than heating equipment. In other words, it can be used as a kind of sanitary tool that kills dust mites on the carpet surface. When used for the purpose of killing mites, the setting is different from that used as a regular warmer, so it can be set to a high temperature while ensuring safety, so it can kill mites efficiently in a short time. be able to.
