Abstract

PURPOSE:To raise the surface temperature of a floor-heating device without heating the contact face between human body and the floor-heating device by providing a switcher with which the supply of electric current to heating resistors is made on and off according to the presence or absence of the human body. CONSTITUTION:The contact of a micro switch 6 is closed usually, and floor heating is made by supplying electric current to many heating resistors. When a human body is positioned on them, the contact of the micro switch 6 in the portion touched by the human body is opened by the weight of the human body, and the supply of the current to the heating resistors 5 in the portion is stopped. Since, however, the current is supplied to the portion not touched by the human body, such an unpleasant condition that the contact face with the human body is heated up can be avoided, even when the surface temperature of the floor heater 3 is raised by a temperature regulator. The portion not touched by the human body is, however, sufficiently heated up for its surface, and therefore room temperature can be raised and sufficient heating feeling can be obtained by the radiant heat to the human body.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a control device for floor heating.

BACKGROUND OF THE INVENTION Conventional floor heating devices of this kind often have a heating resistor 2 wired in series with a floor heating device 1, as shown in FIG. Moreover, even if they are wired in parallel, there is no control for each heating resistor individually.

Problems to be Solved by the Invention However, with the above configuration, when the surface temperature of the floor heating device 1 is increased in an attempt to raise the room temperature, the contact surface between the human body and the surface of the floor heating device 1 becomes hot and hot. There was an inconvenience that it was too much. On the other hand, if the surface temperature of the floor heating device 1 is maintained at a level where the surface that comes in contact with the human body does not become hot, the room temperature will not rise much, resulting in a disadvantage that a sufficient heating sensation cannot be obtained.

The present invention solves such conventional problems, and aims to increase the surface temperature of a floor heating device without heating the contact surface between the human body and the floor heating device.

Means for Solving the Problems In order to solve the above problems, the floor heating apparatus of the present invention is equipped with a switch that turns on electricity to the heating resistor depending on the presence or absence of a human body.

According to the above-described configuration, the present invention turns off the electricity to the heating resistor located on the surface that is in contact with the human body by a switch when the human body is located on the floor heating device, and when the human body is located on the floor heating device, the power is turned off by the switch. By energizing only the heating resistors in the floor, floor heating can be performed without increasing the temperature of the surface that comes in contact with the human body.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 3 denotes a floor heating apparatus main body, and inside thereof, a large number of pairs of heating resistors 4 and 5 are wired in parallel connection. A microswitch 6 is attached to each pair of heating resistors 4 and 5, whose contacts are opened and closed depending on the weight of the human body.

In the above configuration, the contacts of the microswitch 6 are normally closed, and a large number of heating resistors are energized to perform floor heating. However, when a human body is placed on top of them, the microswitch 6 switches the contact point of the microswitch 6. The contact point 6 opens due to the weight of the human body, and the current supply to the resistance heating element 6 in this part is stopped. However, since electricity is supplied to parts that are not in contact with the human body, even if the surface temperature of the floor heating system main body 3 is increased using a temperature controller (not shown), the surface in contact with the human body will become hot. It does not cause any discomfort. However, since the surface temperature of the parts that are not in contact with the human body can be raised sufficiently, the room temperature can be raised by convection heat radiation from these parts, and the radiant heat from these parts to the human body can provide a sufficient feeling of heating. It will be done.

FIG. 2 shows another embodiment for real use. This occurs when one side of the floor heating system main body 3 is long, and there are many heating resistors 4, 5, 7.
．． 8 consists of two circuits 10 and 11. Each pair of heating resistors 4, 5° 7.8 is 10 or 11
The wires are connected in parallel in the 0 circuit, and a micro switch 6.9 is installed. In this case, the human body position is 10
Alternatively, since it is detected by the microswitch 6 or 9 in the circuit No. 11, for example, when the human body is in Zone No. 10, the Zone No. 11 is always energized, allowing fine control.

As described above, the floor heating system of the present invention provides
1 effect can be obtained.

Since the resistance heating elements connected in parallel are equipped with a switch, the power supply to the heating resistance only in the area where the human body is located is stopped, thereby preventing the contact surface between the human body and the floor heating unit from heating up and causing discomfort. It has the effect of preventing it from spreading. This allows the surface temperature of the floor heating body to be kept high, raising the room temperature, and providing a comfortable feeling of heating due to the radiant heat from the floor surface.
