Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor heating system that heats a room by installing a plurality of heater units on the floor.

A conventional floor heating system of this kind is constructed as shown in FIG. 1 to 8 are heater units, each of which has a built-in heating element (not shown). Among these, a temperature sensor 9 is built into the first representative unit. 1o is the cord opening, 1
Reference numeral 2 denotes a power line and a sensor line, which are tangentially connected to a controller 13 that performs temperature control. The heating wires built into heater units 1 to 8 are connected in parallel (not shown) and connected to a power line. Further, 14 is a room temperature sensor, which is connected to the controller 13 with a lead wire 15, and can be installed at any height in the room.

FIG. 2 is a circuit diagram of the conventional example already mentioned, and the room temperature R
It has a function of setting the temperature of the floor heater (hereinafter abbreviated as bed temperature) according to T. The operation will be explained below. In the figure, 16 is a direct current circuit, and 1 is a temperature setting circuit, which inverts and amplifies the voltage VR at the midpoint of the bridge circuit including the room temperature thermistor 18. The room temperature thermistor 18 is the third
The negative temperature characteristics shown in the figure are shown. Therefore, if the room temperature RT increases, the partial pressure VR due to the room temperature thermistor 18 increases,
There is a completely directly proportional relationship in that as the room temperature RT decreases, the VR decreases.

This VR is inverted and amplified with respect to the reference voltage VREF of the inverting amplifier 19. If the output of the inverting amplifier 19 is vF, the relationship between vR and VF is as shown in a of FIG. 4. or,
If vRFJF is changed by the variable resistor 2o, a curve like b or C, which is a slide of the curve of a, can be obtained. Furthermore, the maximum value of VF is limited by the Zener diode 2o. From the above, the relationship between the room temperature RT and the output voltage vR of the temperature setting circuit 17 is as shown in FIG. Next, 21 is a bed temperature detection circuit, which is composed of a bed temperature thermistor 22 and a series circuit of a resistor. The temperature characteristics of the bed temperature thermistor 22 are similar to those of the room temperature thermistor 18, and the characteristic diagram is shown in FIG. Letting the output voltage of the floor temperature detection circuit 21 be VT, when the floor temperature is low, VT has a low value, and when the floor temperature is high, V7 has a high value. 23 is a temperature control circuit, which includes a comparator 24 that compares voltages vF and vT, and a transistor 26 that drives a DC relay coil 26 in accordance with the output thereof.

When the output vF of the temperature 0 degree setting circuit is higher than the output VT of the temperature detection circuit, the output of the comparator 24 becomes HIGH, the output register 26 is energized, and the relay contact 27 is turned on.
L, the heating element 28 is energized. Conversely, when vF is lower than vT, the output of comparator 24 becomes LOW, transistor 26 is deenergized, and heating element 2B is not energized.

To summarize the above, when the room temperature RT is low, vR becomes a low voltage, and as mentioned above, in this case, the temperature setting circuit 1
7 becomes a high voltage, the heating element 28 is energized until the output VT of the temperature detection circuit 21 becomes higher than VF, and the bed temperature FT is controlled to be high. In this way, f was shown as follows.
This is point a in FIG. Father, on the other hand, when the room temperature RT is high,
VR becomes a high voltage, vF becomes a low voltage, and the bed temperature FT is controlled to be low. This corresponds to e in Figure 6.
It is a point.

As mentioned above, floor heating systems with a configuration in which the operating temperature of the floor heater is controlled according to the room temperature mainly use radiant heat to provide warmth in rooms where people sit on chairs, such as Western-style rooms and between wooden boards. As a result, the relationship shown in FIG. 6 is established. To give an example of the data, in Figure 6, point a is a room temperature of 10°C and the bed temperature is 42°C, and point f is a room temperature of 15°C and a bed temperature of 3.
6°C, the point e is the room temperature of 20°C and the bed temperature of 28°C, and if control is performed based on the relationship between the room temperature and the bed temperature, a certain level of comfort can be obtained in the aforementioned Western-style rooms and the like. However, in rooms where people sit on the floor (tatami), such as Japanese-style rooms that are common in Japan, inconveniences arise.

When you sit on the floor and mainly collect heat by conduction heat, you start to feel a little hot when the floor temperature exceeds the human body temperature.
If the temperature exceeds 0°C, you will feel quite hot, and if it continues, you will feel uncomfortable. When using conventional floor heating systems in rooms where people sit and live, such as the Japanese-style rooms mentioned above, the floor temperature rises too much, especially when the room temperature is low, and you cannot expect comfortable heating. . In addition, if the floor temperature is set to a temperature that is comfortable for the human body, the energization rate of the heating element will decrease, and the ability to raise the room temperature will decrease, and the temperature of the room will not rise much, and the heating element will be in contact with the floor. Only one part of me felt warm and the rest felt cold, which made me feel uncomfortable.

The present invention improves these conventional drawbacks,
Even in a room where you live in a sitting position, the heater unit in the sitting area can be set to the user's preferred temperature with a simple operation, and other heater units will automatically adjust according to the room temperature. The purpose of the present invention is to provide a floor heating device configured so that the temperature can be set automatically and the room itself can be heated while the user can also enjoy comfortable warmth.

In order to achieve this object, the present invention includes a first temperature setting means that includes a plurality of heater units and is configured to manually set the temperature, and a second temperature setting unit that is configured to automatically set the temperature according to the room temperature. at least one of the heater units is configured to operate at a temperature according to the output of the first temperature setting means, and the heater unit of the pond is configured to operate at the second temperature setting means. It is equipped with a control means.

With this configuration, the heater unit operated by the first temperature setting means can be operated at a desired operating temperature by manual temperature setting by the user, and the heater unit operated by the second temperature setting means can be operated at an operating temperature that suits the user's preference. The heater unit can be operated at an operating temperature that is dependent on the room temperature, so that a user sitting on the heater unit operated by the first temperature setting means can enjoy a comfortable temperature that suits his or her preference, regardless of the room temperature. In addition to being able to collect heat, from the heater unit operated by the second temperature setting means, it is possible to receive radiant heating using radiant heat that feels comfortable depending on the room temperature, and it is also possible to heat the entire room depending on the room temperature. .

Furthermore, in order to achieve the above-mentioned objects more effectively and with greater ease of use, the present invention provides the first... A designation means is provided which can designate either one of the second temperature setting means.

With this configuration, the user can arbitrarily specify the heater unit on which he or she should sit using the specifying means, and manually set the operating temperature of that heater unit. 1-.

Hereinafter, one embodiment of the present invention will be described using the drawing of FIG. In addition, in Fig. 7, the same circuit as that in Fig. 2 is indicated by d.
They are given the same number. In this embodiment, a case will be described in which there are eight heater units, and each heater unit has a built-in heating element and a temperature sensor. Reference numeral 29 denotes a temperature setting circuit that can be manually set as desired.The specific configuration is as shown in FIG. Partial pressure by 3, 29
The output is taken out from the -4 dividing point. variable resistance 29
By changing the resistance value of -4, the output can be changed. 1 is an automatic temperature setting circuit that changes the temperature setting output according to the room temperature, and performs the same operation as explained using FIG. 2 and FIGS. 3 to 6. 3o is a designation circuit that specifies whether each heater unit (y) is operated at a manually set temperature or an automatic set temperature that is set according to the room temperature, and its specific configuration is shown in Figure 9. The designated circuit is composed of eight blocks corresponding to eight heater units. In the figure, 30-1 and 30-8 are each one block, and 30-2 to 30-7 are omitted. The operation of the designated circuit will be explained using the block 30-1 as an example.

The positive side of the DC current is connected to 30-9, and the ground side of the DC power source is connected to 30-10. 30-11 is a designated switch, and when the contact on the 30-A side is ON as shown in the diagram, the temperature of the heater panel corresponding to this block is automatically set according to the room temperature. To, again,
When the contact on the 30-B side is ON, the following circuit configuration is used so that the temperature can be set manually.

When the contact of the switch 30-11 is on the 30-A side, the transistor 30-11 is energized and the relay coils 30-13, 30-14, and 30-15 are driven. Conversely, when the contact of the switch 30-11 is on the 30-B side, the transistor 30-11 is deenergized and the relay coils 30-13, 30-14, 30-15
is not driven.

Next, returning to FIG. 7, 31 receives the output of the instruction circuit 3o, and the manual temperature setting circuit 17. This is a control circuit that supplies the output of each sheep of the automatic temperature setting circuit 29 to the temperature control circuits 23-1 to 23-sf that control each heater uni-soto according to the specifications, and the specific configuration is as follows. As shown in the figure. Relay contacts 31-1 to 31-8 in the figure correspond to relay coils of blocks 30-1 to 30-8 shown in FIG. 9. The operation will be explained using the contact point 31-1 as an example. At 30-1 in Figure 9, relay coil 3Q
-13 is driven, so that relay contact 31-1-A in FIG. 10 is closed and relay contact 31-1-B is open. Therefore, the output of 31-9 in Fig. 10 is 17
The output of the automatic temperature setting circuit will be supplied. When the switch 30-11 in FIG. 9 is turned on to the 30-B side, the relay coil 30-13 is not driven;
The contact of 31-1-A will be open, the contact of 31-1-B will be closed, and 31-9 will be supplied with the output of the manual temperature setting circuit. Below, 31-1 corresponds to each block of designated circuits 30-2 to 30-8 in FIG.
From 0 to 31-16, either the output of the automatic temperature setting circuit 17 or the manual temperature setting circuit 29 is supplied in the same manner. Next, returning to FIG. 7, the temperature detection circuit 32 will be explained. . The specific configuration of the temperature detection circuit 32 is as follows.
Shown in Figure 1. In the figure, thermistors 32-1 to 32-8 are temperature sensors built into each heater unit l). A DC power supply is connected between 32-9 and 32-10, the voltage is divided by a thermistor and a resistor, and the resulting partial voltage is taken out as a temperature signal for each heater panel. This temperature signal is input via relay contacts 32-11 to 32-18 to a circuit 32-19 that outputs the average value of the input voltage.

Relay contacts 32-11 to 32-18 correspond to blocks 30-1 to 3o-8 of the designated circuit in FIG. 7, respectively, and in the case of 30-.1, relay coil 30-14 is not driven. For example, relay contact 32-11 in FIG. 11 will close. Therefore, in the designation circuit 30, the temperature signal of the heater unit designated for automatic temperature setting based on the room temperature has an average voltage of -.

It is input to the determining circuit 32-19, and its average value is obtained. Also, relay contacts 32-21 to 321-"
2"7 also corresponds to blocks 3o-1 to 30 of the designated circuit in FIG.
-8, and in the case of 30-1, when the relay coil 30-15 is driven, the relay contact 32-20-A in Fig. 11 is closed and the relay contact 32-20-B is opened. The average value signal is obtained from 32-28 as the output of the temperature detection circuit. Conversely, if relay coil 30-15 in FIG. 7 is not driven, relay contacts 32-20-A are open, 32-20-33 are closed, and
A temperature signal corresponding to the thermistor 32-1 is output to the output 32-28. In this way, the outputs 32-28 of the temperature detection circuit 32 correspond to each block of the designated circuit in FIG.
~32-35, for heater units whose temperature is manually set, a temperature signal returned from each thermistor built into the corresponding heater unit is output, and other temperature signals are automatically set according to the room temperature. The average value of the temperature signals obtained from the individual thermistors built into the corresponding heater unit is output to the heater unit that sets the temperature. Next, return to Figure 7...23-1
23-8 are temperature control circuits corresponding to each heater unit, and the specific configuration is similar to the circuit shown at 23 in FIG. 2, and the operation is as described above. Taking 23-1 as an example, when manual temperature setting is specified in block 3o-1 in the designated circuit 30, the output of the manual temperature setting circuit 29 is output from 3-1-g as the output of the control circuit 31. Output is selected and output. Further, the temperature detection circuit outputs a temperature signal obtained from a thermistor built into the corresponding heater unit to 32-28. In response to these two signals, the temperature control circuit 23-1 connects the relay contact 33
-1 is turned on and off, thereby heating element 34-1
The energization is controlled so that the operating temperature is set by the manual setting circuit. Further, in the designation circuit 3o, when automatic temperature setting in which the temperature is set according to the room temperature is designated in block 3o-1, the output of the automatic temperature revision circuit 17 is output to 31-9. Also, from the temperature 0 degree detection circuit, the average value of the temperature signals obtained from the thermistor built in the heater unit specified for automatic temperature setting is 3.
2-28. Depending on these two signals, the temperature control circuit 23-1 turns on and off the relay contact 33-1.
By doing so, the power supply to the heating element 34-1 is controlled so that the operating temperature is set by a temperature setting circuit that automatically sets the temperature according to the room temperature.

In this way, by providing the automatic temperature setting circuit 17 that sets the temperature according to the room temperature and the manual temperature setting circuit 29 that allows the temperature to be set manually to set the operating temperature of each heater unit, the user can You can warm up by sitting on the heater unit that is operating at your preferred temperature, and the operating temperature of the other heater units is determined according to the temperature of the room, making it possible to automatically heat the room comfortably. - There is still a designation circuit 3o that specifies manual temperature setting or automatic temperature setting for each heater unit, and a control circuit 31 that supplies one of two types of temperature setting signals to the temperature control circuits 23-1 to 23-8. By providing this, the user can specify any heater unit to take heat at a desired operating temperature at a desired location, and also can heat the room using other heater units.

As described above, according to the floor heating device of the present invention, the heater unit that operates by manual temperature setting can be operated at an operating temperature that suits the user's preference by manually setting the temperature by the user, and , a heater unit that operates with automatic temperature setting can be operated at an operating temperature that corresponds to the room temperature, so a user sitting in a heater unit with a manual temperature setting can enjoy the comfort that suits his or her preference regardless of the room temperature. In addition to being able to take in warmth, the heater unit that operates with automatic temperature settings can provide radiant heating that feels comfortable depending on the room temperature, and can also heat the entire room depending on the room temperature.

Furthermore, by making it possible to specify either manual temperature setting or automatic temperature setting for each individual heater unit, the user can easily adjust the temperature setting according to the usage conditions such as when things are placed in the room. Depending on which heat knee you should sit on.

Second, you can manually set the operating temperature of the heater unit to your desired temperature by specifying the desired temperature.
