[0002]

2. Description of the Related Art In a floor heating apparatus for heating a room, a floor panel is used as a heating panel in which a heating element such as a hot water tube is disposed. In a floor heating apparatus, a control device for starting and stopping the floor heating, setting the floor temperature, and controlling the floor temperature. And a heat source that supplies thermal energy to the floor heating panel by wire, and a floor temperature sensor is provided near the hot water outlet of the hot water tube of the floor heating panel, and the temperature detected there is measured. A method of transmitting data to the control device by wire has been used.

[0003]

In the above-mentioned conventional floor heating system, the temperature sensor is of a contact type, and the floor temperature is controlled by the temperature of the place where the temperature sensor is installed. There is a problem that it is fixed and does not always match the place of human beings in daily life, and since the control device and the temperature sensor are connected by wire, the installation is troublesome, and if the temperature sensor is temporarily fixed on the floor surface Even if they are arranged in contact, there is a problem that the signal code is in the way. The present invention seeks to solve these problems.

[0004]

A floor temperature monitoring device comprising an infrared temperature sensor, a transmitting means for converting a temperature detected by the sensor into a wireless transmission signal and emitting the signal, and receiving the wireless transmission signal And a controller for controlling the amount of energy supplied to the floor heating unit so that the output of the unit becomes a set target.The monitoring device is separated from the floor surface. It can be installed anywhere.

FIG. 1 shows an entire embodiment of the present invention. F is a floor panel with a floor heating panel through which a tube is passed. One to several units are stretched in one room to form a floor of the room. B is a bath water heater, which circulates hot water through the pipe P to the floor heating unit. C is a control device mounted on a wall W or a pillar in the room. In FIG. 1, the control device is mounted on the wall of the room where the floor heating is performed, but it need not be mounted in the same room, but may be in an appropriate place. The control device C and the gas water heater B are connected by wire, and the temperature or flow rate of the hot water sent from the gas water heater B to the floor heating unit is controlled by a signal from the control device C. S is a monitoring device, which is attached to the lower surface of the top plate of the desk T in the case of the example of FIG. 1, but is installed at an arbitrary place in a room where floor heating to be temperature-controlled is performed. It can be changed arbitrarily.

The first feature of the present invention is that the monitoring device S, in particular, the temperature sensor therein is installed in a non-contact manner so as to look away from the floor surface and look down on the floor surface. That is, electromagnetic waves or ultrasonic waves are used as a wireless transmission means because the wireless communication means is connected to the control device wirelessly. An infrared temperature sensor is used as the temperature sensor.

FIG. 2 shows a monitoring device. Reference numeral 1 denotes a case, on which a suction cup 2 is mounted on the back. Reference numeral 3 denotes an infrared temperature sensor, 4 denotes an oscillator, and 5 denotes an A / D converter which converts the output of the infrared temperature 3 into a digital signal. Reference numeral 6 denotes a modulator which modulates the output of the oscillator 4 in accordance with the output signal of the A / D converter, and emits it from the antenna 7 as an electromagnetic wave. Reference numeral 8 denotes a rechargeable power supply device which is detachably attached to the monitoring device S and is detached from the monitoring device and inserted into an indoor outlet for charging while floor heating is stopped.
Instead of making the power supply device 8 detachable, the entire monitoring device may be directly inserted into an outlet to charge the power supply device 8. In the case of FIG. 2, the monitoring device S is attached by the suction cup 2. If the place to be attached is a smooth surface such as a plastic surface, a metal surface, or a tile surface, the monitoring device S can be sucked as it is. Then, it is difficult to adsorb using only the suction cup. In this case, a plastic sheet 9 coated with an adhesive on one side may be attached to a surface to be attached, and the monitoring device S may be sucked to the surface of the plastic sheet by the suction cup 2. When using ultrasonic waves for signal emission, the oscillator 4 is an ultrasonic oscillator,
The antenna 7 is a speaker for emitting ultrasonic waves.

FIG. 3 shows a control device C. Since the control device C is fixed, it is connected to the commercial power supply by the electric wire 9 and power is supplied to each unit via the power supply circuit 16. A receiving circuit 10 receives a signal emitted from the monitoring device S. The received signal is information on the temperature of the floor surface being monitored, which is held in the register 11. The target temperature set by the temperature setting key 13 on the operation panel 17 is stored in the register 12. The temperature information is periodically transmitted from the monitoring device S, so that the contents of the register 11 are periodically rewritten. Reference numeral 14 denotes a comparator,
And 12 are compared, and when the floor surface temperature is higher than the target value, a command to stop the gas supply of the burner is issued from the command device 15 to the water heater, and when the floor surface temperature is lower than the target value, the gas supply start command is issued. Is issued. These commands are performed by wire. The bed temperature control turns on the gas supply of the water heater
Instead of turning it off, it may be performed by circulating and stopping the circulation of hot water of the floor heating panel.

The infrared temperature sensor 3 used in the monitoring device C has a monitoring area of a constant solid angle ω as shown in FIG. 2 and detects the average temperature within the solid angle ω. It doesn't matter what the slope is. In this temperature sensor, the temperature is calibrated with the temperature measurement target surface as a black body, and since the actual temperature measurement surface is not a black body, the output of the temperature-sensitive semiconductor is multiplied by a correction coefficient, and the floor used is The output of the heating panel is obtained at a constant temperature, and the coefficient is adjusted so that the indicated value becomes the constant temperature. In the monitoring device S, the adjustment knob 31 adjusts a variable resistor (not shown) in the infrared temperature sensor circuit.

[0010]

According to the present invention, the floor temperature is controlled by detecting the floor temperature. The fact that the floor heating is not controlled by the room temperature is used. The main feature is that a non-contact method is used. First, the warmth caused by floor heating is obtained directly from the floor temperature rather than room temperature. If floor heating is effective, the room temperature itself will feel warm even if it is quite low, so the allowable range of room temperature will be very wide, If it is attempted to control the floor heating by heating, there is a danger that the floor temperature may become too high and cause a low-temperature burn. In this regard, a method of directly controlling the floor heating by directly detecting the floor temperature is excellent. There are two ways to detect the floor temperature: a method of detecting the floor temperature by attaching a temperature-sensitive element somewhere on the floor heating panel and a method of detecting the floor temperature non-contactly. The temperature of the place where the temperature-sensitive element is installed is detected, and it is difficult to grasp the overall average temperature of the floor surface.The appropriate place to install the temperature-sensitive element is selected from the structure of the floor heating panel. It is difficult to select an appropriate place for convenience of use. For this reason, it is easy to occur that the control is performed by detecting the temperature of a place different from the surface where the person lives on a daily basis. As a result, excessive or insufficient heating occurs. Since the present invention uses an infrared temperature sensor having a function of detecting a temperature in a non-contact manner, the temperature sensor can be installed at an arbitrary place where a place where a person is present can be seen. Therefore, bed temperature control is most appropriately performed. In addition, according to the present invention, since the temperature sensor and the control device are wirelessly connected to each other, it is not necessary to route the signal line, and the installation of the floor heating equipment is simpler than the contact temperature detection method, and the installation location of the temperature sensor It is also very easy to change
