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. Since it is directly heated, it has the advantage of increasing the wall temperature and suppressing cold radiation and cold drafts from the wall, creating an ideal air-conditioned space.However, since the floor itself is a heat radiator, If the surface temperature of the floor heating panel is not set below a certain limit, excessive conductive heat will be applied to the part that comes 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 radiated from the floor will decrease, resulting in a lack of heating capacity, and as a result, it will be necessary to use it in combination with other heating methods. It had the disadvantage of not being able to take full advantage of its strengths.

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

The present invention provides a floor heating panel that is divided into a plurality of sections and has a heater that can be individually energized in each section, and a section provided in each section of the floor heating panel,
a pressure sensor that detects the presence or absence of a human body; a room temperature sensor that detects room temperature; a plurality of energization control means that are connected to the heaters of each of the compartments and are operated by the output of the room temperature sensor; energization amount setting means each connected in parallel to the energization control means and capable of setting the amount of energization to the heater in each of the sections, and switching to the energization control means when a human body is not present in the section based on the output of the pressure sensor; and a changeover switch that switches to the energization amount setting means when a human body is present in the section. According to this configuration, when a section of the floor heating panel is under pressure, that is, when a human body is in contact with the panel, the pressure sensor detects this, and the section detects the panel surface temperature. Adjusts the temperature manually or automatically to a comfortable temperature. Conversely, in areas where the pressure sensor does not detect the load, the surface temperature is automatically controlled to release the amount of heat commensurate with the heating load of the room, based on the room temperature detected by the room temperature sensor. This makes it possible to realize a comfortable heating effect by taking advantage of the advantages.

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

In FIG. 1, reference numeral 1 denotes a floor heating panel having an electric heater inside, and is provided with a room temperature sensor 2 for detecting indoor temperature, and a controller 3. The floor heating panel 1 has a plurality of sections a, b, It is divided into c... FIG. 2 shows a cross-sectional view of the floor heating panel 1,
It is composed of a heater 4, a sheet-shaped piezoelectric material 5 as a pressure sensor, 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

Controls the amount of electricity supplied to a, 4b, 4c...

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 is activated by the changeover switch 9.
A is maintained on the 10a side, and 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. Conversely, when no human body is on section a, no load is applied to the piezoelectric material 5a, and the changeover switch control signal generation block 8a switches the changeover switch 9a to the on/off switch 12a side to adjust the surface temperature of section a. On/off control is performed via the on/off switch control circuit 11 based on a signal from the room temperature sensor 2 so that the indoor temperature reaches a preset indoor temperature.

Therefore, the temperature of the part of the floor heating panel 1 that is in contact with the human body is controlled to a temperature that allows the resident to obtain the desired conduction heat, and the other part is controlled to the indoor temperature that the resident feels comfortable. ability to be 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, for the resident's preferred surface temperature setting in the compartment where pressure is detected,
By detecting the surface temperature of the floor heating panel and automatically adjusting the amount of electricity, and by detecting the temperature of the part that comes in contact with the human body and controlling the amount of electricity within a range that makes the human body feel comfortable. A similar effect can be obtained.

As described above, the floor heating apparatus of the present invention provides the following effects.

(1) A floor heating panel that is divided into multiple sections and has a heater that can be individually energized in each section;
A pressure sensor that is provided in each section of the floor heating panel to detect the presence or absence of a human body, a room temperature sensor that detects room temperature, and an output of the room temperature sensor that is connected to the heater of each section. a plurality of energization control means operated by;
An energization amount setting means is connected in parallel to the plurality of energization control means and is capable of setting the amount of energization to the heater in each of the sections, and the energization control is performed when a human body is not present in the section based on the output of the pressure sensor. Since the device is equipped with a changeover switch that is switched to the energization amount setting means when a human body is present in the compartment, the human body position is controlled while controlling the surface temperature to correspond to the heating load of the room according to the room temperature. It detects and sets only the floor surface temperature of the relevant section to a temperature that is comfortable for the human body to come in contact with, thus solving the problem of insufficient capacity due to the limitation of floor surface temperature, which was a drawback of conventional floor heating equipment. Underfloor heating alone can resolve the conflicting demands of raising room temperature and maintaining an appropriate temperature for areas that come into contact with the human body.

To supplement this point, if you try to raise the room temperature to a specified temperature using only a floor heating system in a room with a general heating load, the temperature of the floor surface will be lowered by the human body coming into contact with it in order to ensure the required heating capacity. The temperature was too high (for example, about 50 degrees Celsius) compared to the comfortable temperature (for example, the floor surface temperature was about 35 degrees Celsius), and there was a risk of low-temperature burns if the product was in contact for a long time. The surface temperature limit in floor heating is due to direct contact with the human body, and there is no problem even if the non-contact parts are relatively high temperature.

Even though the area where the human body comes into contact with the floor is small compared to the whole area, the heat output of the floor heating system is limited by the temperature of this area.
Conventional floor heating systems, whose surface temperature is set to about 35°C to match the human body, have difficulty heating the entire room. The present invention solves this problem.

(2) Compartments where the human body is not present are usually at a higher temperature than conventional floor heating systems, so radiant heat has a greater effect of heating the human body and the surrounding walls than a method that heats only the human body, creating a comfortable state. At the same time, unpleasant cold drafts from the wall can be suppressed.

(3) It has the heating capacity to raise the indoor temperature to a predetermined level, and there is no need to use auxiliary heating, so there is no unpleasant feeling of air current that occurs when convection heating is used as an auxiliary heat source. It is.

(4) Since the surface temperature of the floor heating system other than the position of the human body can be made sufficiently high, the time and area ratio of operation at maximum capacity are large, especially at the start of operation, and it has good start-up characteristics.

(5) When the user enters the room, the room can be warmed by energizing the floor heating system in advance, so the user can immediately feel the heating sensation. In particular, when the human body is cold, the comfortable temperature of the floor surface is higher than when it is steady, so when the room heating load is maintained at a higher temperature than the comfort temperature during steady state, the comfort level is high. In addition, since the temperature of the compartment gradually decreases after the human body is located, the drop in floor temperature coincides with the change in comfortable temperature due to the warming of the human body, providing a comfortable heating effect even in a transient manner. obtain.
