[Function] The hot carpet of the present invention includes a carpet body with a built-in heater, a sensor for detecting the presence or absence of a person or a pet on the carpet body, and a heater power supply based on a detection signal from the sensor. Since the structure is equipped with a control section that controls ON/OFF and the temperature of the carpet body, the heater power can be turned on only when there is a person or pet on the carpet body, thus reducing power consumption. You can save money.

In this case, the carpet body is divided into a plurality of blocks, the heater and the sensor are provided for each block, and based on the detection signal from the sensor, the heater power source is turned on and off and the temperature of the carpet body is controlled for each block. Since the structure is equipped with a control unit that controls the temperature, the heater power is turned on and the heater temperature is controlled only in blocks where people or pets are present, and all other blocks except that block have their heater power turned on. O
It is possible to switch to FF or to maintain the temperature of the carpet body at a temperature lower than the set temperature, thereby further reducing power consumption.

[0012] In addition, in this case, the structure is such that the sensor section consisting of the plurality of sensors is separated and independent from the carpet body and can be moved and installed at any position on the carpet body. If the location where a person, pet, etc. is located above is specified, the sensor section can be appropriately installed at that specific location, and therefore,
There is no need to incorporate many sensors into the carpet body.
The number of parts can be reduced.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a hot carpet according to a first embodiment of the present invention.

The hot carpet in Example 1 has a carpet body 1 which has a built-in heater over its entire surface. Pressure sensors 2 are embedded in scattered spots over the entire surface of the carpet body 1, and these pressure sensors 2 detect the presence or absence of a person, pet, etc. on the carpet body 1 by pressure, and transmit this detection signal via a lead wire 3. It has a function of outputting to the control section 4. This control section 4 has a function of controlling ON/OFF of the heater power source and the temperature of the carpet body 1 based on the detection signal from the pressure sensor 2.

To explain the operation of the first embodiment, in the hot carpet having the above structure, when there is a person or a pet on the carpet body 1, the pressure sensor 2 at that location is activated.
detects this, and based on this detection signal, the control section 4 turns on the heater power, quickly raises the temperature of the carpet body 1 over the entire surface of the carpet body 1, and maintains it at the set temperature.

When a person, pet, etc. disappears from the carpet body 1, the pressure sensor 2 at that location detects this, and based on this detection signal, the control section 4 turns off the heater power.

[0018] In this way, the heater power is turned on only when there is a person, pet, etc. on the carpet body 1, and therefore power consumption can be reduced.

FIG. 2 is a perspective view showing a hot carpet according to a second embodiment of the present invention.

The hot carpet in Example 2 has almost the same structure as that in Example 1, but the carpet body 1 is divided into a plurality of blocks 5, and a heater and a pressure sensor 2 are embedded in each block 5. Based on the detection signal from this pressure sensor 2, the heater power is turned on and off.
It is also characterized in that it is provided with a control section 4 that controls the temperature of the carpet body 1 on a block-by-block basis.

When there is a person, pet, etc. on the carpet body 1, the pressure sensor 2 of the block 5 detects this, and based on this detection signal, the control section 4 turns on the heater power of the block 5. , the temperature of the carpet body 1 is controlled, and in all other blocks 5 except this block 5, respective heater power is turned off or the temperature of the carpet body 1 is maintained at a temperature lower than the set temperature.

When a person, pet, etc. disappears from the carpet body 1, the pressure sensor 2 of the block 5 detects this, and based on this detection signal, the control unit 4
turns off the heater power of all blocks 5.

[0023] In this way, only the block 5 in which a person or a pet is present is turned on the heater power to control the temperature of the carpet body 1, and in all other blocks 5 except that block 5, the heater power is turned on. OFF
Alternatively, the temperature of the carpet body 1 can be maintained at a temperature lower than the set temperature, and therefore power consumption can be further reduced.

FIG. 3 is a perspective view showing a hot carpet according to a third embodiment of the present invention.

The hot carpet in Example 3 has almost the same structure as that in Example 1, but is applied when the position of a person, pet, etc. on the carpet body 1 is specified, It is characterized in that it is equipped with a sensor section 6 consisting of a plurality of pressure sensors 2, and that this sensor section 6 is separated and independent from the carpet body 1 and can be moved and installed at any position on the carpet body 1.

When a kotatsu is made at the center of the carpet body 1, the sensor section 6 is installed at approximately the center of the back surface of the carpet body 1, or is attached using Velcro.

[0027] In this way, when the position of a person, pet, etc. on the carpet body 1 is specified, the sensor section 6 can be appropriately installed at the specified position. In addition to the effects, it is not necessary to incorporate a large number of pressure sensors 2 into the carpet body 1, and the number of parts can be reduced.

Although the invention made by the present inventor has been specifically explained based on examples, the present invention is not limited to the above-mentioned examples, and can be modified in various ways without departing from the gist of the invention. Needless to say.

For example, in the above embodiment, a pressure sensor is used as a sensor for detecting the presence or absence of a person or a pet on a carpet. It can also be used to optically detect the presence or absence of people, pets, etc. on the carpet.

[0030]

[Effects of the Invention] Among the inventions disclosed in this application, the effects obtained by the typical inventions are briefly explained as follows.
It is as follows.

(1). The structure includes a sensor that detects the presence or absence of a person or pet on the carpet body, and a control unit that controls ON/OFF of the heater power and the temperature of the carpet body based on the detection signal from this sensor. Only when there are people or pets on the carpet,
The heater power source can be turned on, and power consumption can therefore be reduced.

(2). In the case of (1) above, the carpet body is divided into a plurality of blocks, the heater and sensor are provided for each block, and based on the detection signal from the sensor, the ON/OFF of the heater power source and the temperature of the carpet body are blocked. Since the structure is equipped with a control unit that controls each unit, the heater power is turned on only in blocks where people or pets are present, and the heater temperature is controlled.
In all other blocks except that block, the respective heater power can be turned off or the temperature of the carpet body can be maintained at a temperature lower than the set temperature.
Therefore, power consumption can be further reduced.

(3). In the case of (1) above, the structure is such that the sensor section consisting of the plurality of sensors is separated and independent from the carpet body and can be moved and installed at any position on the carpet body, so in addition to the effect of (1) above, When the location of a person, pet, etc. on the carpet body is specified, the sensor section can be appropriately installed at that specific location, so there is no need to incorporate a large number of sensors in the carpet body. The number of parts can be reduced.
