Description

[Detailed description of the invention] The present invention relates to a method of controlling a floor heating device.

Traditionally, floor heating systems have a nearly uniform temperature distribution and almost no airflow, so there is no inconvenience such as hot heads and cold feet or the feeling of cold air caused by the airflow, and the surrounding walls are directly heated by radiant heat. This has the advantage of creating an ideal air-conditioned space by increasing the wall temperature and suppressing cold radiation and cold drafts from the wall, but since the floor itself is a heat radiator, it is difficult to use underfloor heating panels. If the surface temperature is not set below a certain limit, excessive conductive heat will be applied to the parts that come into contact with the human body, causing discomfort.

Therefore, in a typical room, if the surface temperature is kept within a comfortable range, the amount of heat dissipated from the floor surface will be reduced, resulting in insufficient heating capacity, and as a result, it will be necessary to use other heating methods in combination. It had the disadvantage of not being able to take full advantage of its strengths.

The present invention solves the above-mentioned conventional drawbacks, and aims to achieve a comfortable heating effect without imparting excessive conductive heat to the human body while obtaining sufficient heating capacity through floor heating. .

In order to achieve this object, the present invention divides a floor heating panel of a floor heating device into a plurality of sections, arranges a pressure sensor in each section, and further provides a room temperature sensor for detecting room temperature, and further provides a room temperature sensor for detecting room temperature. A control device is provided for identifying and controlling a section where the panel surface temperature is variable based on the signal from the pressure sensor and a section where the panel surface temperature is automatically controlled according to the signals from the pressure sensor and the room temperature sensor.

According to this configuration, in a section with floor heating panels,
A pressure sensor detects the presence of pressure, i.e. when a person is in contact with the panel, and the compartment manually or automatically adjusts the panel surface temperature to a comfortable temperature for the occupant. .

On the other hand, in areas where pressure sensors do not detect loads, the advantages of underfloor heating can be taken advantage of by automatically controlling the surface temperature to release the amount of heat commensurate with the room's heating load based on the room temperature detected by room temperature sensors. This makes it possible to realize a comfortable heating effect.

Hereinafter, an embodiment in which the surface temperature of the section where pressure is detected is manually varied in the present invention will be described with reference to FIGS. 1 to 3.

In Fig. 1, reference numeral 1 denotes a floor heating panel that has an electric heater inside, a room temperature sensor 2 that detects the indoor temperature, and a controller 3.
The floor heating panel 1 is divided into a plurality of sections a, b, c, . . . . FIG. 2 shows a sectional view of the floor heating panel 1, and shows the heater 4. The pressure sensor is composed of a sheet-shaped piezoelectric material 5 and a heat insulating material 6. FIG. 3 shows a control circuit of the control device 7 in the controller 3. Each section a, b, c... is each independently made of piezoelectric material #+sa,

sb, ac... are piezoelectric materials sa, sb, sc
Switches 9a and 9b are activated based on the signals from .

. . . and a variable resistor 10 for manually varying the panel surface temperature for each section where the pressure is detected.
On the a, 10)), 10c... sides, room temperature sensors 2 that detect indoor temperature are installed for compartments that do not detect pressure.
The heaters 4 a , 4 b , 4 C . . .
・Switches 12a, 12b, 12 that turn on and off electricity
c... side, heaters 4a, 4b,
4c... Controls the amount of current supplied.

To explain the operation of section a in the above configuration, when a human body is on section a, a load is applied to the piezoelectric material 5a, and in this case, the changeover switch control signal generation block 8a holds the switch 9a on the 10a side, The surface temperature of section a is controlled according to a set surface temperature (resistance value of variable resistor 10a) set in advance according to the resident's preference.

In addition, when there is no human body on section a, no load is applied to the piezoelectric material 5a, and the changeover switch control signal generation block 8a switches the switch 9a to the on/off switch 13a side to adjust the surface temperature of section a in advance. On/off control is performed via the on/off switch control circuit 11 based on the signal from the room temperature sensor 2 so that the set indoor temperature is reached.

Therefore, the temperature of the part of the floor heating panel 1 that the human body comes into contact with is controlled to a temperature that allows the occupant to obtain the desired conduction heat, and the other parts are controlled to a temperature that makes the occupant feel comfortable. is controlled.

Therefore, there is no problem of insufficient capacity unless used in conjunction with other heating means, and it is possible to fully utilize the features of the floor heating system, such as good temperature distribution and almost no airflow.

In addition, as another example, this method detects the surface temperature of the floor heating panel and automatically adjusts the energization amount according to the surface temperature setting of the resident's preference in the compartment number ζ where the pressure is detected,
The human body feels comfortable by detecting the temperature of the part that comes into contact with the human body.
A similar effect can be obtained by controlling the amount of current within the range.

As is clear from the above description, the floor heating device of the present invention divides the floor heating panel into a plurality of sections, arranges a pressure sensor in each section, and further includes a room temperature sensor that detects the room temperature.
Based on the signal from the pressure sensor, a section in which the panel surface temperature is variable and a section in which the panel surface temperature is automatically controlled in accordance with the signals from the pressure sensor and the room temperature sensor are identified and controlled. The presence or absence of a human body on the unheated panel is detected, and the contact area between the human body and the panel is adjusted to the temperature f41 ((IJ,
The heating capacity of other parts can be controlled to maintain an indoor temperature that is comfortable for the occupants. Therefore, there is no need to use other heating methods during floor heating, so the temperature distribution is good, there is almost no airflow, and the surrounding walls are heated by radiant heat (thereby suppressing cold radiation and cold drafts). Figure 82 is a front sectional view of the same panel, and Figure 3 is a cross-sectional view of the same panel. It is a control circuit diagram of a control device.
